    Classification: Unclassified

I get an "internal compiler error: Arithmetic exception" for:
//////////////////////////////////////////////
#define ARRAY_SIZE 6

void bug(int var[ARRAY_SIZE]) {
    int i;

    for (i = 0; i < ARRAY_SIZE; i++) {
        var[i] = i;
    }
}
//////////////////////////////////////////////
if ARRAY_SIZE is >= 6 when compiling it with
x86_64-w64-mingw32-gcc -O2 -fgraphite -c
or
x86_64-w64-mingw32-gcc -O3 -fgraphite -c

Using built-in specs.
