             Bug #: 56185

           Summary: [4.7 Regression] ICE for Arithmetic exception with -O2

                    and -fgraphite

    Classification: Unclassified

           Product: gcc

           Version: 4.7.2

            Status: UNCONFIRMED

          Severity: normal

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
