https://issues.dlang.org/show_bug.cgi?id=22752 Issue ID: 22752 Summary: _d_delThrowable() may crash if a foreign Throwable object is being finalized by the GC Product: D Version: D2 Hardware: All OS: Windows Status: NEW Severity: normal Priority: P1 Component: druntime Assignee: nobody puremagic.com Reporter: frame86 live.com It's currently possible to return a Throwable object from a D-DLL and throw it in the main application. While this is questionable use case - it's also a workaround for the poor DLL-support because throwing from a DLL function directly crashes. However, while earlier builds just crashes immediately if a foreign Throwable object was thrown now the Throwable can be thrown but a timed bomb is plant in _d_delThrowable() which causes the program later to crash if the GC decides to finialize it later. --
