Here is the code:
/*
 * This gives me a SIGSEGV when compiled with -floop-optimize on PPC w/3.3
 * chlunde at ifi.uio.no
 */
#include <math.h>

typedef unsigned int uint;

int main(int, char**)
{
  const uint size = 181; // 180 and lower seems to work
  unsigned char data[size][size];

  for(uint x = 0; x < size; ++x)
  {
    for(uint y = 0; y < size; ++y)
    {
      int intensity = (int)(x * 10.0); // This is needed
      data[y][x] = (intensity >= 0) ? 0 : 1;
    }
  }
}
