The reason you're getting HASH(0x334ca0)-4-5 from your test program is 
that you have a bug in your test program.  Since you only posted your test 
program, that's the only thing we can help you with.

If you post your *real* code, or at least describe what problem you are 
having with push in your *real* code, then we can help you solve your 
*real* problem.

What are you doing in your real program, what do you expect to see, and 
what are you actually seeing?
