Exception error

[John Reinking]

When Windows reports the Problem signature, like the one below when my app crashes, can the "Exception Offset" help me find the offending line of my compiled PB code?

I've got a threading problem that eludes me, and a dual core PC will crash my app, given enough time, every time.

Problem signature:

• Problem Event Name: APPCRASH
• Application Name: Daub32_Test.exe
• Application Version: 0.0.0.0
• Application Timestamp: 00003039
• Fault Module Name: DAUB32.DLL
• Fault Module Version: 0.1.0.0
• Fault Module Timestamp: 00003039
• Exception Code: c0000005
• Exception Offset: 000572f4
• OS Version: 6.0.6000.2.0.0.256.4
• Locale ID: 1033
• Additional Information 1: b9a4
• Additional Information 2: 75bf43dd15ab850c1bd7cf4f28d1e328
• Additional Information 3: b840
• Additional Information 4: 41259a02215e6f58a0d0cdc1461a066a

Running it through a debugger (such as OllyDbg) may help if you know assembler. If you have the code, you could also compile the DLL as an EXE and run it through the PB debugger.

Not to forget: #TOOLS ON and TRACE is your friend.

Are there any command line switches for PBWIN.EXE that put me near the Exception Offset without having to RUN the code?:ven:

No.

That was a really nice feature of PB/DOS, but Windows Doth Giveth and Windows Doth Taketh Away.

Besides... as discussed many, many, many times here... just because a program generates a protection fault at "Point A" (your offset), it does not mean that is where your programming error is.. i.e., relating the compiled offset to a line of source code is not silver bulllet.

In my experience a c0000005 exception means that somewhere you are accessing memory that isn't yours anymore.

Um, that would be everyone's experience, because that's what code c0000005 means.

Well, actually it means the memory is not yours, period, regardless if it ever was yours or not.
