$title 'Trigger unexpected cmexRC error' (CMEXRC01,SEQ=675)

$onText
Using the 'Debug=1967' command line option one can simulate an unexpected crash
of CMEX. This test verifies that the GAMS executable catches this crash as
"Unexpected cmexRC" on Windows, which is defined by the exit code 407. On Unix
we expect an "Could not spawn GAMSCMEX" error with exit code 400.
