Per bug 21182, I tried upgrading gcc from 3.2.... to 3.3, and glibc from 2.3.2-r1 to 2.3.2-r2. I get a segv from gcc 3.3 when trying to merge glibc: CPP='gcc -E -x c-header' /home/portage/portage/glibc-2.3.2-r2/work/glibc-2.3.2/buildhere/elf/ld-linux.so.2 --library-path /home/portage/portage/glibc-2.3.2-r2/work/glibc-2.3.2/buildhere:/home/portage/portage/glibc-2.3.2-r2/work/glibc-2.3.2/buildhere/math:/home/portage/portage/glibc-2.3.2-r2/work/glibc-2.3.2/buildhere/elf:/home/portage/portage/glibc-2.3.2-r2/work/glibc-2.3.2/buildhere/dlfcn:/home/portage/portage/glibc-2.3.2-r2/work/glibc-2.3.2/buildhere/nss:/home/portage/portage/glibc-2.3.2-r2/work/glibc-2.3.2/buildhere/nis:/home/portage/portage/glibc-2.3.2-r2/work/glibc-2.3.2/buildhere/rt:/home/portage/portage/glibc-2.3.2-r2/work/glibc-2.3.2/buildhere/resolv:/home/portage/portage/glibc-2.3.2-r2/work/glibc-2.3.2/buildhere/crypt:/home/portage/portage/glibc-2.3.2-r2/work/glibc-2.3.2/buildhere/nptl /home/portage/portage/glibc-2.3.2-r2/work/glibc-2.3.2/buildhere/sunrpc/rpcgen -Y ../scripts -c rpcsvc/bootparam_prot.x -o /home/portage/portage/glibc-2.3.2-r2/work/glibc-2.3.2/buildhere/sunrpc/xbootparam_prot.T make[2]: *** [/home/portage/portage/glibc-2.3.2-r2/work/glibc-2.3.2/buildhere/sunrpc/xbootparam_prot.stmp] Segmentation fault make[2]: Leaving directory `/home/portage/portage/glibc-2.3.2-r2/work/glibc-2.3.2/sunrpc' make[1]: *** [sunrpc/others] Error 2 make[1]: Leaving directory `/home/portage/portage/glibc-2.3.2-r2/work/glibc-2.3.2' make: *** [all] Error 2 I USE nptl, and run a current 2.5 kernel.

Can you try with -O2 instead of -O3 please ?
-O2 results in the same error as -O3. .../buildhere/elf/ld-linux.so gives a SEGV for any command that does not end up displaying its help text. I got this trace by running the command in gdb (the corefile did not have the info): Program received signal SIGSEGV, Segmentation fault. 0x80001c6b in dl_main () (gdb) where #0 0x80001c6b in dl_main () #1 0x8000f902 in _dl_sysdep_start () #2 0x80000f7e in _dl_start () I had a breakpoint at dl_main() and the SEGV occurred after just one step command.
Resolving as WORKSFORME, as glibc-2.3.2-r2 is rather old. glibc-2.3.2-r6 is in portage, and I've built it using gcc-3.3.1 with nptl and a 2.6.0-testX-mmY kernel many times without incident. Thus, it was likely fixed upstream in glibc CVS. If this is not the case, feel free to re-open this bug.
