Description of Problem:
Compilation of attached file with certain optimization flags causes this
internal compiler error:
Internal compiler error in verify_local_live_at_start, at flow.c:583
Steps to Reproduce:
1. Compile attached source with this command line:
gcc -fexpensive-optimizations -funroll-loops -falign-functions=4 -O3
-march=athlon -mcpu=athlon -fschedule-insns2 -fno-gcse -c B2DPlugin.c -o xx.o
Above compiler error is given; gcc quits.

Preprocessed C source to trigger gcc optimzation bug
This bug is also triggered with the simpler command line:
gcc -O3 -fno-gcse -c B2DPlugin.c -o xx.o
I've just checked the current state of redhat branch of gcc-3.2
(gcc-3_2-rhl8-branch). The bug was gone (I've used two option
combinations mentioned by the customer). So I am closing the bug.
