I just encountered a strange bug that I'm having problems reproducing as a 
test case.

I used an associative array to store some data lengths, and in my code, I 
was accessing an element not in the array. In debug mode, this code did not 
fire ArrayBoundsError and worked (returning 0 I guess), but in release mode 
it crashed. Any ideas why this might have happend?

Did you check that "invariant", "unittest" and "in/out" of in/out/body
have no side effects appart from debugging output?

"aa[non_existant]" should allways throw an exception however
"non_existant in aa" simply returns null.

Yes.

 "non_existant in aa" simply returns null.

Yes. The problem is that the exception wasnt raised in the debug build.

Was the key to the AA a char[] and do you .dup the key when you store values? 
If not, is it possible that you have modified the char[] you used for the key,
this can have some unexpected results and behaviour.

That's all I can think of.
