To: gcc-bugs
Consider:
char a[8][8];
char b[8];
void
foo (int i)
{
int j;
for (j = 0; j < 8; j++)
{
a[i][j] = 0;
b[j] = j;
}
}
I get:
$ ./cc1 -quiet -O2 -ftree-loop-distribution min.c
min.c: In function 'foo':
min.c:5: internal compiler error: in build2_stat, at tree.c:3298
Please submit a full bug report,
with preprocessed source if appropriate.
