Hey there, I'm currently using NetBeans 6.8 running Cygwin GNU Bash version 3.2.49(23)-release. I'm having a problem running my program that uses pthreads, mutexes, and semaphores. After it creates 1 to 3-4 threads, it returns a Segmentation fault. I ran the program on a computer running Linux (using NetBeans as well) and had no issues running (i.e. didn't return Segmentation fault). Is there a fix for this problem? I also tried debugging in NetBeans but after the program starts creating threads, I try to select threads from the "Threads" tab in the debugging menu, but would not let me step into one thread at a time, and then gives me a Segmentation Fault error message. So I was also wondering if there was a solid way to debug multi-threads on NetBeans. Thank you for your help.
