At a quick guess, this sounds to me like an threading library, OS or
compiler specific issue.

What OS and version are you using? If Linux what kernel version? What
compiler are you using?

Also, I don't know how your Debug routine is implemented, is it
possible the Debug routine is somehow causing problems? Maybe some
sort locking or deadlock condition?
