AW: [Quickfix-developers] Re: ThreadedSocketAcceptor Segmentation Faults

[Bill R. Hr. <bil...@ra...>]

The strange behaviour ... you aren't alone, we experience on our test =
system
(SUSE Linux, MySQL, gcc 3.4.3) the same (random) failure. Only your =
analysis
of the problem is much better than ours!

Thanks and regards,

Also note that the thread that FIX::thread_detach() receives is 0. I =
think
that's the segfault cause. Also i think the threads are joined =
previously,
when Acceptor::stop is called. The threads are detached when the
Socket->Read() loop ends and so the thread does.=20

If this strange behaviour is happening only to Alberto and me we really
should start looking at dependencies and installed libraries to =
determine
where the incompatibility may lay on.

I really think this call should be changed to a thread_join, at least =
on
UNIX systems.  Detaching a running thread seems like playing Russion
Roulette to me.
