oh please. turn your cflags down and try again.
try again but with less insane CFLAGS/CXXFLAGS for example, use just '-pipe'
Well, just to throw my two cents into the good ol' Signal 11 debate... before you reply back that your CFLAGS work for everything else and your hardware is of good quality, please take a moment to visit: http://www.bitwizard.nl/sig11/ and read it. Now having read some of the information there. Try backing your CFLAGS down to something a bit more sane. One very problematic CFLAG is -mfpmath=sse,387, it's even mentioned as a bit troublesome in the GCC docs. Pick either SSE or 387 floating ops. Personally, I use SSE. Also, -msse -mmmx, -msse2 are redundant as they are set by -march=pentium4. The next CFLAG you might want to change is -Os to -O2, that occationally can fix issues. However it is important to note that backing your CFLAGS all the way down to the safest levels (i.e. "-pipe") might not fix this problem. As the problem could be in a poorly compiled glibc or gcc or any other binary/library that the groff compile uses. Basically, signal 11 is telling you that somewhere there is a code path with a bad memory address in it due to a failure in hardware or in the compiling process from those CFLAGS.
Ok, the problem was "-Os", changing it to -O2 solves the problem : it compiles with CFLAGS="-march=pentium4 -O2 -mtune=pentium4 -msse -msse2 -mmmx -mfpmath=sse,387 -fomit-frame-pointer -ffast-math -funroll-loops -pipe" (And for the redundancies, it's for ebuilds that filter some flags such -mtune or -march...)
what if you try with just -Os
It works with CFLAGS="-Os" but fails with CFLAGS="-march=pentium4 -Os"
Same here, on x86 (my CFLAGS being "-march=pentium4 -Os -pipe -fomit-frame-pointer -funroll-loops -falign-functions=4") it fails with the same error. After removing "-march=pentium4" from CFLAGS, groff compiles nicely.
How about with just CFLAGS="-march=pentium4" CXXFLAS="-march=pentium4" Does this still fail?
That seems to work. I'm going to try compiling with -march=pentium4 and each flag, one at a time.
Ok, several other tests revealed that this bug only occurs when -march=pentium4 and -Os are in CXXFLAGS together. BTW, I'm using gcc 3.4.2.
As far as I'm aware, gcc-3.4.x still has SSE2 issues. In particular, it is often the case that certain optimisation steps break SSE2. If you try compiling groff with CFLAGS that will ensure that all the binaries won't run on your system (so perhaps "-march=athlon-xp" or something like that) you'll see that the "Illegal instruction" error shows up at this very same point. Effectively, this means that your groff binary got lost somewhere up its own arse and thus has been miscompiled. A possible solution would be to append "-mno-sse2" to the CFLAGS (or is it CXXFLAGS?). Also, on any architecture with a version of GCC less than 4.0-cvs on any 32-bit architecture, -mfpmath=387 is faster than -mfpmath=sse, which in turn is faster still than -mfpmath=sse,387. The fastest situation is leaving -mfpmath unset, which is also therefore the most stable (because that's what all the GCC devs use - unset). So unless you're deliberately trying to break things and slow them down, or have an AMD64 or Nocona chip, get rid of -mfpmath.

groff now changes -Os into -O for everyone (previously was just alpha)
