1. Under MS VC++ (only tested with version 6.0), a term_func
- set via the standard C++ set_terminate() function is not called
- for some reason. The code in private.c ptw32_threadStart()
- retrieves and calls the user supplied terminate routine, which
- works as expected under MinGW32 g++, but doesn't run under
- MS VC++ 6.0, presumably because set_terminate() returns NULL.
+ set via the standard C++ set_terminate() function is not called.
+
+ Notes from the MSVC++ manual:
+ 1) A term_func() should call exit(), otherwise
+ abort() will be called on return to the caller.
+ A call to abort() raises SIGABRT and the default signal handler
+ for all signals terminates the calling program with
+ exit code 3.
+ 2) A term_func() must not throw an exception. Therefore
+ term_func() should not call pthread_exit(), which
+ works by throwing an exception (pthreadVCE or pthreadVSE)
+ or by calling longjmp (pthreadVC).
+
+ Workaround: avoid using pthread_exit() in C++ applications. Exit
+ threads by dropping through the end of the thread routine.
