Re: Thread crash in destructor

see below – scanning my own info I realized:

>>Thread 4 Crashed:
>>0 libboost_thread.dylib 0x000000010e4a4570 tls_destructor + 96

... that it linked to a dynamic lib which I did not intend to – I am using a static lib and this made me conclude that I had a path issue so it eventually linked to a wrong lib which eventually caused the issue.

After fixing my paths the issue is resolved and it works perfectly fine even with the latest 1_77

Sorry for the confusion and thanks for your help !

Now it would be nice to focus on the thread priority which might possibly be wrong as well.   

Best

Hej Juan,

thanks for the quick response !

>>Are you sure detach() and join() do not help?

Yes, I checked it several times. I put either tracerouteThread.join() or tracerouteThread.dispatch() right after launching it but it resultet in the same effect.

Please find the OSX-report here – thread 4 is the one that crashes (just in case: My app uses Qt):
