sorry guys, figured out that it's some problem in my data structure.

It's true though that this error haven't shown up when the program was
compiled normally.  There's a flag I forgot to initialize at the beginning
of the program, which, if is non-zero, will trigger the errorous portion
of the program.  That part of the program is not supposed to be verified 
until the next stage of development.

sorry again.
