I'm running a multithreaded program in LabWindows CVI 7.1. There are four threads in my program with: - reads and writes on RS232 - reads and writes with DAQmx 8.6.0f5 to a module USB6008 I sometimes have the following error in debug mode and release mode.: FATAL RUN-TIME ERROR Unknown source position, thread id 0x00000E88 A non-debugger thread Caused a 'General Protection ' fault at address 68647163. Is there a way under CVI 7.1 to know what's the problem ?
I'm running my programm under this PC:
Windows XP / Version 2002 / SP3
Processor = 2.7 Ghz
RAM = 3Go
Thank you for your help,
I don't know if we can debud or spy a FATAL RUN-TIME ERROR, I need verify.
Can you try on a more recent LabWindows/CVI version ?
Have you an simple example that reproduce the error ?

thank you for your prompt response.
I don't have a simple exemple that produces the error.
When I simulate USB6008 and RS232 commands, the program don't produce any error.
I will first do a test by installing the application on another PC this week.
Il the error occurs, I will create the program with CVI 8.0 and test it.
