Craig,

The obstacle is that the debug information IDL is providing gives me
nothing to go on about where to locate the /0. MEAN is called directly
in only about 20 places in the code I am looking to debug, but I
strongly suspect that some other IDL "builtins" call MEAN as well.

How can I get the stack trace of math errors, rather than just the
useless information that MEAN was called with a bad input?
