C source code

I just tried to compile the package xblast-2.10.4 with the latest trunk
snapshot 20110702 on an AMD x86_64 box.

The compiler said

cfg_game.c: In function 'RetrieveAnyGamePlayers':
cfg_game.c:464:1: internal compiler error: Floating point exception
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

gdb says

Program received signal SIGFPE, Arithmetic exception.
0x0000000000cf7007 in vector_alignment_reachable_p (dr=0x14f5150)
    at ../../src/gcc-4.7-20110702/gcc/tree-vect-data-refs.c:1114

(gdb) p stmt_info
$1 = (struct _stmt_vec_info *) 0x15490c0

Preprocessed source code attached. Flag -O3 required.
