Faulting module ntdll.dll error in net10

Bevan Thomas 0

I have an application which has both its 32-bit and 64-bit variant.I recently retargetted it to net10 from net8.64-bit application works fine.But the 32-bit application crashes with following error -:

Faulting module name: ntdll.dll, version: 10.0.19041.6456, time stamp: 0x5f1a1fa5

Exception code: 0xc0000374

Fault offset: 0x000f4b53

Faulting process id: 0x8f8

Faulting application start time: 0x01dcb207f3ab8556

The error happpens where we call managed code from unmanaged code.

The exception code indicates that the underlying issue resulted in heap corruption. The likely cause is a marshaling problem between the managed and unmanaged code (pinvoke or COM interop). There's nothing specific that can be diagnosed in the absence of more detail about the executing code.
