Created attachment 1418 [details] minimal example that crashes Hi, When a thread is created from C++ (or probably any other language) and this thread calls back to a D function which deals with exceptions (even if they are properly caught), the program will crash. Here is the stack: #0 0x000000000041f469 in thread_stackBottom () #1 0x000000000041ee5a in core.runtime.defaultTraceHandler() () #2 0x000000000041ee01 in core.runtime.defaultTraceHandler() () #3 0x000000000041e6a1 in _d_traceContext () #4 0x000000000041bf78 in _d_createTrace () #5 0x0000000000417872 in _d_throwc () #6 0x000000000041746d in test.throwit() () at test.d:15 #7 0x00000000004173fe in callback() () at test.d:6 #8 0x00007ffff7bd956d in std::_Bind_simple<void (*())()>::_M_invoke<>(std::_Index_tuple<>) (this=0x647708) at /usr/include/c++/4.9/functional:1700 #9 0x00007ffff7bd94b5 in std::_Bind_simple<void (*())()>::operator()() (this=0x647708) at /usr/include/c++/4.9/functional:1688 #10 0x00007ffff7bd9432 in std::thread::_Impl<std::_Bind_simple<void (*())()> >::_M_run() ( this=0x6476f0) at /usr/include/c++/4.9/thread:115 #11 0x00007ffff6eac8a0 in ??

Just run build_and_gdb.sh which will compile the c++ library, the d program and start gdb on it.
