Unexplained crashes related to ntdll.dll

I have an application that I've written that crashes intermittently, but I'm unable to capture an exception at the application layer. I always get an entry in the event log but doesn't give me much info:

Faulting application name: BCS-UI.exe, version: 1.0.11.0, time stamp: 0x5c0edcbd

As you can see, I get this:

Faulting module path: C:\WINDOWS\SYSTEM32\ntdll.dll.

I'm not sure what that is or how it relates to the crashes, but I've been able to reproduce it on multiple machines and I'm at a loss on how to determine the cause or prevent it from happening.

Update: I've gotten to a point where the application crashes on startup with the above reason. It gets to the end of the MainWindow constructor (it is a WPF application), sits there for about 10 seconds on a white screen and then dies. I've rolled back to older versions of the software and reproduced this behavior. I have also moved it to another machine and did NOT see this behavior, so my current theory is in agreement with what was said in the comments - that something corrupted the heap and it only gets cleared up on a reboot.

Update 2: I'm able to produce this error message when running outside of the debugger, although when running in the debugger, I'm not able to get it to stop on an exception:

a generic error occurred in GDI+

So that's what I'll be hunting today. Interestingly and disturbingly enough, the app crashes every time on startup, even after rebooting. The same behavior does not occur on other machines at this time.

To debug these kind of system internal issues, I suggest you try Process monitor

Process Monitor is an advanced monitoring tool for Windows that shows real-time file system, Registry and process/thread activity.

Basically you need to look out for the "NAME NOT FOUND" errors, which means missing dlls or registry keys, or any other suspisious errors in the monitor screen.

The last time I had a similar crash in my app that pointed to ntdll.dll as the faulting module, the reality was that my own code had a memory leak. I did a strcpy on a string that was not allocated memory. Something like,

char * str;
strcpy(str, "Hello");

I found this after a strenuous walkthrough of my code.

Check your code for leaks.
