Same problem with gcc 2.96rh, 3.1.1, and current CVS
>Description:
My system almost seems cursed! Please note that about 95% of the files that I compile, do compile correctly, the remaining 5% get: the internal error: Segmentation fault, always on the same files with the same configuration, therefore, I don't beleive it to be a problem with my computer. However the problem can be fixed usually by changing compilation options, for instance, by changing a -O99 or -O3 to an -O2 or -O, it will sometimes compile correctly. Also adding a -fomit-frame-pointer, removing -Wall, or doing a -E to preprocess and then a -x cpp-output, will sometimes fix the problem. I've tried several different compiler builds including 2.96rh, 3.1.1, and the CVS builds, all have the same problem. I can compile with the same compilers on my pentium-mmx laptop and pentium 4 without having any problems, which leads me to beleive that the problem exists with the athlon-xp or kt266a combination, or both? I have tried running both the linux 2.4.18 and 2.4.19 kernels, changing the ulimit on my stack size to unlimited, and tons of other compiler tweaks, without being able to get it to make a difference. I have attached some examples of the problem just from compiling glibc-2.2.5, the problem has also occurred in compiling several other projects. Please let me know if you can get this to reproduce elsewhere, before I go crazy! Thanks, Jason
>How-To-Repeat:
Try it with the same hardware configuration if possible
>Fix:
No definite fixes that I know of beyond changing compiling options (pain in the rear for a lot of projects)
