.NET Forum / Languages / Managed C++ / September 2007Release version crashes on the Multi-CPU system
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.  SignatureDoug Semler, MCPD a.a. #705, BAAWA.

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