Application Verifier break message

Attempt to use a released COM interface

Probable cause

A COM interface was used after it was released.

Troubleshooting Steps

Try to identify the routine that tried to use the released COM interface:

  • Dump the current stack trace by using the 'k' command in the debugger

  • Identify the routine that tried to use the released interface.

Use the dps command with the second parameter of the stop if available to dump the stack trace of the routine that released the COM interface.
