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 Alex 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.

The behavior changed in BOOST_THREAD_VERSION 3 (which is default in boost 1.77). Are you sure detach() and join() do not help?

Can you provide a call stack?

Hi all,

I had been using an old boost system and boost thread lib for a couple of years without upgrading it since approx. 2014. With this old lib the following (simplified) code works fine on OSX:

#include "test.h"

test::test() { boost::thread::attributes attrs;

/// START TRACEROUTE THREAD #if defined(BOOST_THREAD_PLATFORM_WIN32) res = SetThreadPriority(attrs.native_handle(), THREAD_PRIORITY_NORMAL); #elif defined(BOOST_THREAD_PLATFORM_PTHREAD) pthread_attr_setschedpolicy(attrs.native_handle(), SCHED_FIFO); #endif tracerouteThread = boost::thread( attrs, boost::bind(&test::performTraceroute, this)); }

void test::performTraceroute() { cout << "START TRACEROUTE" << endl;

string exec = ""; cout << "DO FURTHER STUFF BUT THIS IS JUST A DEMO ..." << endl; cout << "THREAD OVER" << endl; }

Using the current boost 1_77 still does execute the thread but then it crashes within the destructor. Adding

tracerouteThread.join() or .detach() after launching the thread does not help either.

Can anyone help how to resolve this issue ?

Thanks a lot in advance, best

Alex
