Description Matti Niemenmaa 2007-02-03 04:09:51 UTC 
Probably related to Issue 720 in some way, as it's the same error: "Internal error: ..\ztc\cod1.c 2526".

void main() {
	cast(void[])[1];
}

This test now passes with DMD 1.041 and 2.026.

Comment 3 Robert Clipsham 2009-11-07 08:01:58 UTC 
This test case is failing in dmd 1.051. The ICE has gone, but the result at runtime is incorrect.

----
module dstress.run.b.bug_cod1_2528_C;

int main(){
        auto x = cast(void[])[1];
        return x.length - 1;
}
----

Returns 3 instead of 0.
Comment 4 Don 2009-11-13 04:12:15 UTC 
The DStress test case is incorrect. The arrray literal is an int, so it's 4 bytes. Casting it to void[] should give a length of 4 -- and that's exactly what it does.
