Is it possible for an exception to bubble up if catching the general Exception?

Question

Let's say we have C# called by an unmanaged C++ application. The caller's code is unavailable.

public void MethodCalledByUnmanagedCode()
{
try
{
   DoWork()
}
catch {}//assume we swallow exception, no logging or anything
}

In this case, is there any way possible for any exception to bubble up to unmanaged C++ in any circumstance?

@pst - there are reports of exceptions bubbling up in exactly this circumstance. I want to know how that is possible. Note that there is a logging mechanism that will be plugged in here. — P.Brian.Mackey, Jun 23 '12 at 18:21

Your code could raise a ThreadAbortException.

ThreadAbortException is a special exception that can be caught, but it will automatically be raised again at the end of the catch block.

+1. Note that with some effort automatice re-throw could be prevented. – Alexei Levenkov Jun 23 '12 at 18:07

There are also exceptions that will never make to your exception handler like StackOverflowException in normal circumstances.
