The compiler is successful however unit tests are hanging (cpp_thread_safe_test, cpp_container_test, c-refcount-tests, c-reactor-tests, , cpp-example-container). All tests except cpp-example-container seem to have the same failure. I am willing to debug this further if needed but maybe you guys already have some hints at why it might be hanging (I tend to think there is an object not added or destroyed correctly and this its reference is not being incremented or decremented). Debugging analysis so far: * c-refcount-tests: The hanging is occurring when calling the first drain in test_collector_connection_transport ( drain(collector) ) * cpp_thread_safe_test: The hanging is occurring when calling the last assert in test_new ( ASSERT_EQUAL(1, pn_refcount(c)) ) Failures with stack (pstack $PID | c++filt) ================================= c-refcounts-tests ------------------------ fffffd7fff2efd87 pn_collector_next () + 2f 00000000004023e2 drain () + 1e 0000000000402464 test_collector_connection_transport () + 74 00000000004027f5 main () + 45 00000000004014bc ????????
