hi all, i''ve got a very strange problem in my program, sometimes it crashes with a simple call to new. I really don''t know why it doesn''t work. Why calling new could fail ? i don''t think it could be a memory problem, because there''s much memory left when the code crashes. Is there a reason why new could fail ? I use Visual studio 6.0, and the code allways crashes after _heap_alloc_base( ), in NTDLL! ... does anybody got an idea about what this problem could be ? i really need help, i''m so confused with this thanks.

Nobody can say much of anything without code and errors/messages.

You might need to replace your heap.

Go to your closest computer hardware store and ask them if they have a memory heap, possibly also a new stack.

Alternatively you could just download a new heap from the internet and print it with your printer. Just insert the paper(after some cutting) in your processor and off you go, to the afterworld probably.

Most likely, the problem is that you are writing past the ends of another allocation and overwriting heap manager data.
