Subj : Re: exit_group: unfinished ... exit status 144 To : comp.programming.threads From : annamalai.gurusami Date : Thu Aug 18 2005 06:22 am Just wanted to add one more information. The above problem happens only if I cancel all the threads that is spawned by the process in the atexit handlers. If all the threads are cancelled before calling exit(0), then everything is working fine. .
