Release version crashes on the Multi-CPU system

[Guest]

I have a C++/C++.net application. Release version crashes on the Multi-CPU
box but Debug version works well. And release version works well on
single-cpu box.

Any idea?

I have a C++/C++.net application. Release version crashes on the Multi-CPU
box but Debug version works well. And release version works well on
single-cpu box.

Any idea?

As I tell my coworkers:

More information is needed than just "my application crashes". What is the
error message? Are you getting an exception? Is it hanging? Is it a GUI
program that's doing cross thread calls into controls improperly? Have you
attached a debugger to the release version and tried trapping the exception?
Are you a multithreaded app, and if so are you using shared resources
properly (i.e. volatile members, locks, monitors, Interlocked increments,
etc).

It's probably a cross thread variable examiniation that isn't interlocked
properly on the multiprocessor machine or a cross thread GUI call.

Yup, one would require other information to even tell what is happening.

Basically it is always good to give callstack of the failing application and
as Doug said, more information will be always useful to give fast resolution.
Atleast that was my experience when I was a support engineer in VC/C# support
team.
