Created attachment 85534 [details] compiler preprocessed sources
fails with 4.1 and 4.2
Created attachment 85713 [details] gcc-4.1-speex-ICE.c
Created attachment 88491 [details] Another test case, using ARTS. I found the same bug, on 4.1.1. This time, the package that ICEs is Arts. The softest compilation options I found that reproduce it are: gcc -O2 -c -ftree-loop-linear arts-sigsev.c Using -O1 instead compiles all right. Disabling -ftree-loop-linear compiles all right too, with -O3 and very agressive CFLAGS. I suppose -O1 doesn't turn on some optimization required for tree-loop-linear.

*** Bug 146011 has been marked as a duplicate of this bug. ***
4.1.2 and 4.2.2 both seem to work. Can someone else please verify this as well?
gcc version 4.1.2 (Gentoo 4.1.2 p1.0.2) gcc version 4.2.2 (Gentoo 4.2.2 p1.0) these both work.
4.1.2 is stable, so this should be fixed now.
