Description William Keaney 2007-09-01 16:50:16 UTC

When running an emerge -e system on a freshly unpacked 2007.0 hardened tarball, gcc fails to build citing an illegal instruction.

Reproducible: Always

Steps to Reproduce:
1.Set up a hardened system
2.Emerge gcc
3.Fail

Actual Results:  
/var/tmp/portage/sys-devel/gcc-3.4.6-r2/work/gcc-3.4.6/gcc/crtstuff.c: In function `__do_global_dtors_aux':
/var/tmp/portage/sys-devel/gcc-3.4.6-r2/work/gcc-3.4.6/gcc/crtstuff.c:288: internal compiler error: Illegal instruction


Expected Results:  
gcc should finish compiling

I am building this system in a chroot on a non-hardened machine; I originally tried to use distcc to build everything, but turned it off when gcc failed.  Disabling distcc did not change the failure at all.

This is the build.log from my latest compile attempt.

D'oh.  Forgot that, even in a chroot, -march=k6-2 won't work on a pentium-m system.  Closing, invalid.
