Unhandled c++ exception in one thread is supposed to bring down the
whole process, correct ?

Sometimes we observe that unhandled c++ exception kills the thread,
the process continues (other threads).

What could cause process not being killed by unhandled c++ exception
in one thread ?

Thanks

Setting up your own unhandled exception filter. Though you're strongly
discouraged from doing so.

As this the above link says, default unhandled exception handler calls CRT
exit(). I observed cases when calling exit() in multi-threaded program
didn't cause process to terminate. On the other side, Win32 ExitProcess()
always worked for me - never saw it hang. Behaivior of CRT exit() can be
modified, by calling onexit() for example - if onexit() handler hangs,
process will hang.
Also, SEH exceptions don't cause C++ exceptions to be thrown and are handled
by SEH handler (also see Win32 SetUnhandledExceptionFilter()).
