Original post is at bottom of this.

I checked. I did have "\n" in the printf.

When I run this from the DOS prompt, no error messages show.  I am
merely tossed out of the program to the DOS prompt.

The source is proprietary.  I can't show it.  I would have to cobble
something that duplicates the problem.  Kind of makes it tough to ask
intellegent questions :-(  Furthermore, if I could duplicate the problem
in a small program then I could fix it myself, nicht war?

When the act of loading a program into the debugger fixes a runtime
problem, is the 'fix' usually due to changed memory alignment due to the
fact that the target is loaded into a different place in memory?

| is your program actually crashing?  If so, try a "\n" at the end of
the

More: -------- DOS prints no error messages. Just dumps me at the
prompt.
