The following testcase crashes the mainline compiler when compiled with
"-msse2 -fmudflap -ftree-vectorize -O3" on i686-pc-linux-gnu:
====================================
int a[16];
void foo()
{
int i;
for (i = 0; i < 16; i++)
a[i] = i;
}
====================================
bug7.c: In function 'foo':
bug7.c:9: error: invalid operand to binary operator
vect_vec_iv_.27
bug7.c:9: internal compiler error: verify_stmts failed
Please submit a full bug report, [etc.]
