Query on coredump in signal handler

[edu.mvk]

Hi,

I'm facing a coredump in my code in a signal handler inside the
function "__pthread_alt_unlock", could you please help me giving
inputs on this issue, below is the signal handler looks like:

void SignalHandler::sig_chld(int signo, siginfo_t *sip, void *extra)
{
//post a event to let AM main thread handle the sigchld
sigChildEvent* event = new sigChildEvent( sip->si_pid,sip-

>si_code);

QThread:ostEvent(AM_MainFrame::instance()->signalHandler() ,
event);

if (waitpid(sip->si_pid, NULL, WNOHANG) != sip->si_pid)
{
}

}

And moreover i can see a symbol "__pthread_sighandler" in the
backtrace of the dump, does it mean that the signal handler will be
called in a different thread?

Please give your inputs ASAP. Thanks in advance.

Regards
Kiran.

Within a signal handler, allocating memory (as, for example, with a new statement) is a no-no.
