If I have a routine like this that uses garbage collection and does not
explicitly free its memory:

pro test
compile_opt strictarr

o = list()
; obj_destroy, o

exit, status=1
end

And, run it from the command line like below, I get a strange error:

$ idl -e test
IDL Version 8.4, Mac OS X (darwin x86_64 m64). (c) 2014, Exelis
Visual Information Solutions, Inc.

% Compiled module: TEST.
% Can't return from the main level.
% Execution halted at: $MAIN$ 8

If I uncomment the OBJ_DESTROY, I get what I want:

$ idl -e test
IDL Version 8.4, Mac OS X (darwin x86_64 m64). (c) 2014, Exelis
Visual Information Solutions, Inc.

% Compiled module: TEST.
$ echo $?
1
