SYMPTOMS
Attempting to divide an integer number by zero at run time causes one of the following application error messages to be generated instead of the appropriate run-time error:

Under Windows NT version 3.51:

Application Error - The exception integer division by zero occurred in the application

Under Windows 95:

This program has performed an illegal operation and will be shut down.

If the problem persists, contact the program vendor.

Details:

RESOLUTION
Make sure arithmetic expressions do not include a direct or indirect divide by zero calculation.

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.



Sample Code to Demonstrate Problem
C Compile options needed: none

INTEGER ANSWER, NUMER, DENOM

WRITE (*,*) 'This program should fail with a run-time' WRITE (*,*) 'error. No output other than these three' WRITE (*,*) 'lines should appear'

CALL X (NUMER, DENOM) ANSWER = NUMER/DENOM WRITE (*,*) '**Error! integer division allowed**' WRITE (*,*) 'ANSWER=<',ANSWER,'>' END

SUBROUTINE X(I1,I2) I1 = 123 I2 = 0 END
