I saw the same behavior some time ago when I worked on a pretty fat program
(about 6KB compiled code). Sometimes it worked OK, then I removed my debug
code (some cputs defined by macros) and it hanged miserably... I thought it
was some kind of pointer error, but after reading your posts I'm not very
sure of that... Perhaps some kind of linker (dll) error?
