OK, try to recompile both w/ gcc-3.4.4-r1 first. If that doesn't help, try with -march=i586 and report back.
Didn't I? # emerge -p gcc These are the packages that I would merge, in order: Calculating dependencies ...done!

I'll emerge gcc again, but how has portage's notion of which gcc is installed gotten off-track? Is gcc slotted now? I'm not finding any other gcc binary on the system....
(In reply to comment #2) Uhm, maybe reading the upgrading guide would help (hint: gcc-config) :) http://www.gentoo.org/doc/en/gcc-upgrading.xml
Well, I'll be darned. It's still actually 3.3.6 on the Athlon, too - although it's not having the Illegal instruction problem. That's what I get for running periodic emerge -u system sessions and not sitting there staring at every message that goes by, I guess. Back in my day, there weren't all these safety measures. Life was more fun.
(In reply to comment #4) Heh... Well, this is 99% -march=k6-2 issue. Maybe gcc-3.4.4 handles it better, maybe not, and maybe you don't have K6-2 at all (K6 optimizations are really deceptive and it's hard to tell which K6 flavor your CPU exactly is, so best to avoid using it for -march completely).
Two notes: 1 - I tried compiling gmp without march set at all (as I said) - same difference. 2 - I'm real sure this is a K6-2. Built the system myself, back when that was the lastest and greatest CPU. Anyway, probably won't be until tomorrow that I know if the gcc upgrade does it, since that requires recompiling half the system.
Okay guys, I did the full gcc upgrade, and now the system is broken for more critical applications: Cannot load /usr/lib/apache/modules/libphp4.so into server: /usr/X11R6/lib/libgmp.so.3: undefined symbol: __gmpn_com_n I just rebuilt gmp with no flags set at all (no -march), and it stays broken. This is primarily a webserver, so ... not good! It did end up building with -mcpu=i686 (this on a i586) but that shouldn't have broken it (although gcc says mcpu is depricated in favor of mtune...). So: What do I do? I need to get this server back up ASAP. It appears there's a serious bug in the gmp-4.1.4-r3 ebuild when run on the AMD k6-2. Should I revert to an earlier gmp? Should I build again with -mcpu=i586?

Re-emerging at present (straight 4.1.4 with -mcpu=k6-2) At the top of the process it complains about aclocal.m4 being out of date - suggests running a command to update it that doesn't happen to work - so I've gone on with the emerge. Could this be the crux? Hard to find clear documentation on aclocal. I'm looking at http://dev.gentoo.org/~plasmaroo/devmanual/general-concepts/autotools/ at present, but of course that's not advice at the user's level. What's the effective way to update it?
Straight 4.1.4 with -mcpu=k6-2 works! Known not to work: 4.1.4-r3 with -march=k6-2 4.1.4-r3 with implicit -mcpu=i686
Comfirmed clamav now works too.
I just encountered the same problem on a P3. After upgrading to gmp-4.1.4-r3, Clamav died with an illegal instruction exception inside __gmpz_mul_2exp(). Downgrading to gmp-4.1.4 has worked around it for now. # gcc -v Reading specs from /usr/lib/gcc-lib/i586-pc-linux-gnu/3.3.6/specs Configured with: /var/tmp/portage/gcc-3.3.6/work/gcc-3.3.6/configure --prefix=/usr --bindir=/usr/i586-pc-linux-gnu/gcc-bin/3.3.6 --includedir=/usr/lib/gcc-lib/i586-pc-linux-gnu/3.3.6/include --datadir=/usr/share/gcc-data/i586-pc-linux-gnu/3.3.6 --mandir=/usr/share/gcc-data/i586-pc-linux-gnu/3.3.6/man --infodir=/usr/share/gcc-data/i586-pc-linux-gnu/3.3.6/info --with-gxx-include-dir=/usr/lib/gcc-lib/i586-pc-linux-gnu/3.3.6/include/g++-v3 --host=i586-pc-linux-gnu --build=i586-pc-linux-gnu --disable-altivec --enable-nls --without-included-gettext --with-system-zlib --disable-checking --disable-werror --disable-libunwind-exceptions --disable-multilib --disable-libgcj --enable-languages=c,c++,f77 --enable-shared --enable-threads=posix --enable-__cxa_atexit --enable-clocale=gnu Thread model: posix gcc version 3.3.6 (Gentoo 3.3.6, ssp-3.3.6-1.0, pie-8.7.8) CHOST is set to "i586-pc-linux-gnu" and CFLAGS is not set.

I had the same problem, too (also on a K6-2). Playing around with CFLAGS as Whit did didn't help. But I got 4.1.4-r3 to work when I uncommented the line "epatch "${FILESDIR}"/${P}-noexecstack.patch". BTW, as a side-effect the linker warnings about the GNU-stack-notes disappeared.
I have the same issues with 4.1.4-r3 on a Via Samuel procesor. mtune=c3 (my current default) or mcpu=i586 fails to run clamav with an Illegal Instruction. Reverting to 4.1.4 as a fix which seems to work.(In reply to comment #0)
I have the exact same problems here on Via C3. Maybe change the title of the bug, processor type does not seem to be an issue. Using gcc-3.4.4-r1, I manually (ebuild fetch, ebuild unpack, ebuild compile) compiled gmp-4.1.4 and gmp-4.1.4-r3; then as is recommended on the GMP-Library website: http://www.swox.com/gmp/ i did "make check" on both versions. gmp-4.1.4 passed first 53, then 68 tests without error; finishing ok. gmp-4.1.4-r3 aborted after failing the first three tests with illegal instruction. The GMP-Library website strongly discourages using GMP without first running "make check", citing numerous cases of miscompilation with various compilers or versions of GCC. I suggest integrating "make check" into the ebuild or merge process and I would try it, but I have no idea about how to do it. Pointers to examples or information would be welcome. Will now upgrade gcc to 3.4.5 and try again. Will post results.
Now I tried the same thing using gcc 3.4.5. The results are exactly the same.

I get the same problem on my pentium-mmx system, using -march=pentium-mmx . I found this page on the Redhat bugzilla that seems to be a similar problem. https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=118518 Gentoo doesn't seem to have an /usr/lib/sse2, so I'm not sure how to relate the two problems. In my case I solved it by masking gmp-4.1.4-r3 and going back to gmp-4.1.4
