Bug 200089 – [4.1/4.2/ICE] when building mandel with -O1

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Maros Zatko 2007-11-23 16:12:54 UTC]

gcc (GCC) 4.1.2 crashed when I enabled optimization i.e. gcc -O2 mandel.c .
This bug is reproducible on x64_64 platform too.

Reproducible: Always

Steps to Reproduce:
Compilation of my source file with enabled optimizations.
gcc -O2 mandel.c
Actual Results:  
mandel.c: In function 'mandel':
mandel.c:23: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://bugs.gentoo.org/> for instructions.
Preprocessed source stored into /tmp/ccAjeqR9.out file, please attach this to your bugreport.

Expected Results:  
Gcc should compile this file normally.

Reopen once you've attached the sample code to reproduce this, the preprocessed source and emerge --info output.
