Parts of this thread are starting to sound familiar; I am wondering
if I should also be concerned with custom handling of SIGINT....

I have a numerical program that compiles cleanly (DOS 5.0, djgpp 2.03,
gcc 2.7.2.1, bash 2.03), produces the desired results, but displays the
following behavior I've not encountered before:

	- first invocation of program runs completely and correctly.

	- invoke program again, but interrupt it before it completes,
	using Ctrl-C or Ctrl-Break.

	- invoke program again and I get no response, no output,
	nothing.  Must ^C or ^break to regain prompt.  Same for any
	further invocations.

	- HOWEVER, if I execute a simple `ls' after interrupting the
	program, the next invocation *will* run properly.
	
Do these symptoms sound familiar to anyone?
