Hi Martin & Martin,
I've come up with some stand-alone code that I think reproduces the
mutex error I was describing (please see attached C++ code). If you
compile and run this code (requires Linux, 0MQ 1.0.0), you should
eventually see this output:
go
Invalid argument (./zmq/mutex.hpp:97)
Invalid argument (./zmq/mutex.hpp:97)
Aborted
The offending line of code appears to be zmq_mutex_error.cpp:50:
zmq::message_t msg_out( 64 );
If I comment out this line and instead uncomment line 45 (which simply
moves the declaration of msg_out to outside of the while loop) then
the mutex error does not occur. I'm a little hazy on why this is
happening and what the proper 0MQ library usage should be in this
case.
Thanks,
Aamir
