try compiling this package with -march=pentium3 instead of pentium4 also -fomit-frame-pointers is dangerous, the only flags that we know are stable with gcc-3.2.2 are -freorder-blocks and -fprefetch-loop-arrays, and also the ones brought in by -O3 obviously. there are known issues with -march=pentium4, i just want to see if this is caused by that before we try something else
Removing 'pentium4' and replacing it with 'pentium3' did it. BTW - As far as bugs go, I'm not a developer but I've never had any problems using the pentium4 option, nor the omit-frame-pointer. But, then again, what do I know ;-) Thanks -P
*** Bug 16876 has been marked as a duplicate of this bug. ***
added replace-flags "-march=pentium4" "-march=pentium3" to the ebuild
Right, so go add it to glibc, etc, etc as well. Point being, -march=pentium4 is broken, and that is why it was added to make.conf .... problem is that we wont catch it if we filter it in all cases ...
I think -mcpu=pentium4 is a better replacement. I've checked that it works in thise case too. In every case I've looked at it was SSE2 insns from -msse2 enabled by -march=pentium4 that made things blow up. -march=pentium3 will also pessimize code generation for p4's. I also think the comments in make.conf are unsubstantiated. Any case where -mcpu=pentium4 doesn't work?
