A reduced testcase:

void test(byte[] data) {
    data[0] /= cast(cfloat) data.length;
}

void main(){
    byte[1] array;
    test(array);
}

------- Comment #3 from clugdbug yahoo.com.au  2009-04-16 03:35 -------
The bug_cgcod_562_x1 cases have been fixed, but the bug_cgcod_562_x3 cases
remain. This bug accounts for 20% of the remaining Dstress cases which ICE.
Much simpler test case:

void main(){
   int x;
   x/= cast(creal)1;
}

Internal error: ..\ztc\cgcod.c 564

Applies to DMD2.028 as well.

The patch for bug 3059 fixes this.

In fact this bug is now 66% of the remaining dstress cases which ICE, and also
10% of the remaining dstress "unexpected pass" errors...
Of course, it's pretty ridiculous that Thomas put in 36 test cases for this one
bug.
