** Source: pal_except_filter.c (test 3)
**
** Purpose: Tests the PAL implementation of the PAL_EXCEPT_FILTER in the
** presence of a call stack. An
** exception is forced and passed to two nested exception filters for
** consideration. The first filter returns EXCEPTION_CONTINUE_SEARCH
** so the second can run and return EXCEPTION_EXECUTE_HANDLER. The
** initial exception handler should be skipped, and the second
** executed
**
