gcc -O2 -msse -ftree-vectorize -c broken.c -o broken.o

on the code snippet below gives a "broken.c:4: internal compiler error:
Segmentation fault".


extern int array[2][7][6];

void test(int type, int *eq, int idx)
{
  int i;
  int v = type ? 0 : 1;

  for (i = 0; i < 6; i++)
    eq[i] = array[v][idx][i];
