Re: [Valgrind-users] Process terminating with default action of signal 14 (SIGALRM)

[ppmoore <pol...@gm...>]

Hello Tom, thanks for the quick reply.

The signal SIGALRM is handled in the main constructor for the application,
invoked from main(), so I thought that this should be sufficiently quick.

	if (signal(SIGALRM, &signalHandler) == SIG_ERR)
	{
		log_printf(LOG_ERR, "Signal when registering SIGALRM handler\n");
		return -1;
	}

IS there a way top change the default signal-handling in valgrind?

Sorry, about using PS to check for the running application, I was expecting
gdb-link behaviour, where the application being debugged could be observed
in the running process list.
