By default,  when a  'fatal fault'  message is seen in the output of any
testcase,  it is consider an inmediate fatal condition and the test case
is aborted.

However,  in all such cases,  the testcase is provoking the situation to
verify the condition is caught.  In this case it shall NOT be considered
a fatal fault and the default overriden to allow it to proceed.
