Pthreads seems to use real-time signals (32 and higher), and though the documentation for gdb indicates it should be able to handle them, I haven't been able to get it to work. I posted a query about this yesterday called "real-time signals, gdb". It has been suggested to me by another list member that the signal handling code in the Linux kernel may be seriously deficient, and aggrevating if not outright causing this problem. I haven't had a chance yet to look and see if that's the case. Has anyone else had success debugging threads with gdb? -Frank -- Frank H.
