Bug 134710 – [4.1.1/ICE] gcc segfaults compiling ruby-1.8.4.20060226 (ftree-vectorize)

• Product: Gentoo Linux
• Status: RESOLVED DUPLICATE

[Description Piojo 2006-05-28 18:50:18 UTC]

When emerging ruby-1.8.4.20060226 I get an ICE:

regex.c: In function ‘ruby_re_compile_fastmap’:
regex.c:2772: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.

How to reproduce:

i686-pc-linux-gnu-gcc -O3 -march=athlon-xp -pipe -mmmx -m3dnow -msse -mfpmath=sse,387 -maccumulate-outgoing-args -fprefetch-loop-arrays -ftree-vectorize  -fPIC  -DRUBY_EXPORT  -I. -I.  -c  ccI32ToV.c

Reproducible: always.

Created attachment 87772 [details]
The preprocessed source file for ruby's regex.c

[Comment 2 Piojo 2006-05-28 20:26:01 UTC]

It compiles all right when removing -ftree-vectorize CFLAG.
