From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7) Gecko/20040625 Epiphany/1.2.6 Description of problem: I have tried to build various programs on FC3T1 on my home PC which is a K6/2 90% fail nearly immediately with "internal compiler error - illiegal instruction" example kernel make menuconfig scripts/basic/fixdep unable to parse config file internal compiler error - illiegal instruction On my work box I have no problems at all which is a duron (i686) Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: see above Additional info:
You haven't specified which exact gcc rpm you are using. Recently GCC stopped using some prefetch instructions which are supposed to be ignored on arches that don't implement them, but e.g. VIA C3 and maybe K6/2 as well don't comply.
With standard gcc from FC3T1 nothing compiles, pretty much. If I use the compat 33 rpms I have more success, though I still cant get the kernel to compile. (it does get past the make menuconfig stage, but then bombs very quickly, afraid I cant remember the file it fails on)
That's the problem. The gcc change went in gcc-3.4.1-3, i.e. right after FC3T1. Just update to gcc packages from rawhide.
