Description Kai Engert (:kaie) (inactive account) 2006-04-06 18:58:45 UTC 
Description of problem:
internal compiler error: Segmentation fault

Version-Release number of selected component (if applicable):
gcc version 4.1.0 20060304 (Red Hat 4.1.0-3)

How reproducible:

gcc -c -fPIC -Wall -W -Wno-unused -Wpointer-arith -Wcast-align -Wno-long-long
-pedantic -pthread -pipe -O x.c

No ICE if I emit -O


Original command:
gcc -o e_pow.o -c -I../../../dist/include/system_wrappers -include

This seems to work with gcc from rawhide
Comment 3 Kai Engert (:kaie) (inactive account) 2006-04-06 19:20:33 UTC 
To elaborate on my previous comment:

On a Rawhide machine with the same gcc version number installed
   gcc version 4.1.0 20060304 (Red Hat 4.1.0-3)
I do not get an ICE.
Comment 4 Kai Engert (:kaie) (inactive account) 2006-04-06 19:27:28 UTC 
I'm confused. Although I had been able to repeatedly reproduce the problem, I no
longer can. I wonder if my machine got a hardware memory problem. Let me resolve
this as WORKSFORME for now, I'll reopen if I can reproduce again.
