Here is something slightly smaller:
void breakme(int ny, int nx)
{
int* bins[ny][nx], i, j;
for ( i = 0; i < ny ; i++ ) {
for ( j = 0; j < nx; j++ )
bins[i][j] = 0L;
}
}
And there is alread a patch

Here's a testcase with only one loop:
==============================
void foo(int n)
{
int a[1][n], i;
for ( i=0; i<2; i++ )
a[0][i] = 0;
}
==============================
