https://issues.dlang.org/show_bug.cgi?id=13426 Issue ID: 13426 Summary: crash when using exceptions in a non-d thread (in thread_stackBottom) Product: D Version: D2 Hardware: x86_64 OS: Linux Status: NEW Severity: normal Priority: P1 Component: DMD Assignee: nobody@puremagic.com Reporter: blastrock@free.fr Created attachment 1418 --> https://issues.dlang.org/attachment.cgi?id=1418&action=edit 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. -- |
