How to find source of arithmetic error in IDL program?

I am debugging an existing program which appears to fail due to various arithmetic errors.

Program caused arithmetic error: Floating divide by 0

Is there a way to find out what part of the program is producing these errors? Or make the IDL development environment stop when one of these is raised?

Setting the !EXCEPT system variable to 2 will print errors for each statement, showing what file and which line caused the error.

!EXCEPT = 2

% Program caused arithmetic error: Floating divide by 0

% Detected at FUNCTION 77 /home/user/function.pro

The documentation on CHECK_MATH provides more information about how arithmetic errors are handled, in addition to the documentation on math error handling in general.
