Attached code when compiled by gcc version 4.2.0 20060113 (experimental) using
----------
gcc -O1 -fmodulo-sched -ftracer -c insmod.c -o insmod.o
----------
fails like this:
----------
insmod.c: In function ‘main’:
insmod.c:143: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
----------
Tested only on x86. It is a regression since it works on gcc version 4.2.0
20051224 (experimental).

------- Comment #3 from drab at kepler dot fjfi dot cvut dot cz 2006-01-22 01:16 -------
The bug seems to be fixed. (Tested on gcc version 4.2.0 20060121
(experimental)).
Perhaps the fix of bug 25799 fixed this bug. Can anyone confirm?
