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 ?? () from /usr/lib/x86_64-linux-gnu/libstdc++.so.6 #12 0x00007ffff77b30a4 in start_thread (arg=0x7ffff6bdf700) at pthread_create.c:309 #13 0x00007ffff71e7c2d in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:111 I attached a minimal example. Just run build_and_gdb.sh which will compile the c++ library, the d program and start gdb on it. --
