Debugging GP Faults with WDEB386 (77987)
The information in this article applies to:
- Microsoft Windows Software Development Kit (SDK) 3.0
- Microsoft Windows Software Development Kit (SDK) 3.1
This article was previously published under Q77987 SUMMARY
Under certain circumstances, trying to trap GP (general protection)
faults with WDEB386 may produce unexpected results.
In general, if the processor generates a GP fault while a Windows-based
application is running, the GP-fault handler will automatically
provide the mechanism to stop at the offending instruction in WDEB386.
However, unexpected results (breaking at unusual locations, infinite
loops, debugger crashes) may occur under WDEB386 if one of the
following conditions is true:
- The GP fault occurs somewhere other than in a Windows-based application
or dynamic-link library (DLL).
- The WIN.INI file [kernel] section switch DisableGPTrapping is set to
1.
