How do I do that sir? During the 'hang' the gdb is not in control anymore. I mean during the 'hang' there is no
(gdb) prompt to give to backtrace command. I can type it but the gdb will not respont because it has give control to to application (even during the 'hang') Wait.... I have now given a ctrl-z during the hang. now I can give the backtrace command in gdb I hope it now give the right backtrace log. After ctrl-z the output of gdb is: Program received signal SIGTSTP, Stopped (user).
