stack overflow in dmalloc_die

[drok]

Greetings,

I would like to ask if the issue drok/ovpn#7 is known. It appears that when free(pnt=0x0) is called, dmalloc gets into an infinite recursive loop that eventually overflows the process stack.

I have absolutely no experience with dmalloc, so it's possible the error is in my usage; if so, I would appreciate any feedback.

This has been [hopefully] resolved with the addition of a local impl of snprintf. See 313cd95
