** Source:  PAL_EXCEPT_FILTER_EX.c (test 2)
**
** Purpose: Tests the PAL implementation of the PAL_EXCEPT_FILTER_EX. 
**          There is a nested try blocks in this test. The nested 
**          PAL_TRY creates an exception and the FILTER creates another.
**          This test makes sure that this case does not end in a 
**          infinite loop.
