  1. PORandom native exception from .NET Compact Framework 3.5 application
    text
    copied!<p>I have an application written wholly in C# on the .NET 3.5 compact framework that seems to be crashing at random moments with native exceptions. My application never logs any of these exceptions it just quits. Sometimes my application can run for hours or you can start it and 5 minutes later it will crash! </p> <p>I have been storing up the dump files that are sometimes produced but having difficulty understanding what the problem is because I lack debug symbols for the dll that is throwing (netcfagl3_5.dll). The error is an Access Violation but trying to read the output from WinDbg has left me frustrated:</p> <pre><code>FAULTING_IP: netcfagl3_5_7b37d000+152b4 7b3922b4 043092e5 ldr r3,[r2,#4] EXCEPTION_RECORD: ffffffff -- (.exr 0xffffffffffffffff) ExceptionAddress: 7b3922b4 (netcfagl3_5_7b37d000+0x000152b4) ExceptionCode: c0000005 (Access violation) ExceptionFlags: 00000000 NumberParameters: 2 Parameter[0]: 00000000 Parameter[1]: ffffffd4 Attempt to read from address ffffffd4 FAULTING_THREAD: 890fa60a ERROR_CODE: (NTSTATUS) 0xc0000005 - The instruction at 0x%08lx referenced memory at 0x%08lx.
