Subject: Multithreaded programs crashing due to libgcc_s missing
Date: Fri, 06 Jun 2014 16:58:47 +0200	[thread overview]
Message-ID: <5391D727.5020907@suse.de> (raw)

Hi Harald,

I've just uncovered a rather nasty issue with dracut, where for no 
apparent reason a (multithreaded) program was crashing.
Reason being here that libpthread _requires_ libgcc_s when any 
program is using 'pthread_cancel'. When the library isn't present
any of those calls will generate a SIGABRT.
Nasty.

Best would be to pull libgcc_s in always when libpthread is 
required. But that would be some library detection magic.
Can you fix this up?

Cheers,

Hannes
