/**
@file
@brief Testing mp_abort macro
@details This is an unfixed problem with mp_abort when using the
'unclosed macro' technique. This is only relevant for 9.4m3 environments,
which can suffer from hung multibridge sessions from %abort and endsas.
The issue is that when called within a macro, within a %include, AND that
macro contains subsequent logic, the service does not end cleanly - rather,
we see:
ERROR: %EVAL function has no expression to evaluate, or %IF statement has no condition.
ERROR: The macro TEST will stop executing.
We are not able to test this without a 9.4m3 environment, it is marked as
nofix.
