This is new to me, debugging on a FC4 distro.Our large program is not multithreaded or anything like that, but it does depend heavily on a fairly elaborate alarm system invoked with setitimer. In the past (eg., RH9 and older) there has been no problem. But on the FC4 machine, despite "handle all noprint", once I am at a breakpoint every alarm suddenly throws me into the alarm handler, and stepping becomes practically impossible. Suppressing the alarms would require major software changes and disable many functions. I have not been able to find any reference to this problem or how to get around it, though perhaps I simply didn't know where to look or misunderstood what I found. In which case, your patience is appreciated. I suspect I am in big trouble, and I would be grateful for any and all help.
Thanks Jim
