A reduced testcase: void test(byte[] data) { data[0] /= cast(cfloat) data.length; } void main(){ byte[1] array; test(array); }

Fixed dmd 1.023 and 2.007

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.

Fixed dmd 1.048 and 2.033
