Fix dstress.run.b.bug_cod1_2528_C as reported by Don Clugston
Quoting Don's words from Ticket #8:
Fails because it returns 3 instead of 0.
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. Should be "return x.length - 4;".
