I agree with the previous writer that you have probably corrupted your
heap. This can also be caused as a side effect of corrupting your stack
and then any pointers on it. (I've found that corrupting the stack is a
more common problem.)
One way of finding the region of code which is responsible for your
problem is to comment 'chunks' of code until your code works and then
uncommenting smaller chunks until you home into the problem area.
Start with newly written source and hopefully you will find your
problem.
Good luck.
