This article was previously published under Q180709 SYMPTOMS
After you press CTRL+C, a significant amount of code may still be executed
in the primary thread before the program quits.
CAUSE
If there is a read outstanding to a console device and CTRL+C is pressed,
the Input/Output is cancelled and the read is completed. The thread that
issued the read then continues to run. Sometime later, the CTRL+C event is
delivered (in a different thread) to the Control Event handler which
usually causes the process to exit. The problem is that various amounts of
code can execute in the primary thread before the process ever exits. The
amount of code that is executed depends on the platform speed and
processor.
STATUS
Microsoft has confirmed this to be a problem in Windows NT version 4.0. We
are researching this problem and will post new information here in the
Microsoft Knowledge Base as it becomes available.
