callstack - ???

Post by santiago »

Hello madschi,

Hope all if well with you!

We received an exception log that looks like this from a customer:
callstack crc : $a8ed612a, $a8ed612a, $a8ed612a
exception number : 1
exception class : EAccessViolation
exception message : Access violation at address 00007FFB5E0B9C20. Read of address 0000000000000000.

thread $63c:
7ffb5e0b ???
As you can imagine, not very helpful. Any idea, when something like this can happen?

Thank you!

No CPU registers for me?

One thing I can't make out is if this is a 32bit or 64bit process? The list of modules seems to suggest it's 32bit, but the exception message looks like 64bit. One thing that's extremely weird is that the exception message says "Access violation at address 00007FFB5E0B9C20", but the thread callstack says "7ffb5e0b". Notice something there? If you add 0000 + 7ffb5e0b + 0000, you get the "Access violation at address" address. Coincidence? Probably not.

I think this might mean that the crash occurred at address 00007FFB5E0B9C20, which is a 64bit address, but the process might be a 32bit process? This would then be a crash in a Wow64 system dll. Maybe that's why the callback doesn't work? Wild guessing on my part here, though...

Thanks for looking into this madschi.

CPU registers are not present in this particular case.
I do see them in other logged exceptions though.

It is a 64-bit app running on Windows 10-64 bit.

Keep in mind that 64 bit files on 64 Bit Windows are stored in the SYSTEM32 directory.
The 32 bit version of those files are stored in the SysWow64 directory.

What leads you to believe that this could be a 32 bit app?

32bit processes do not know that the files are stored in SysWow64. They think it's System32, as well. So the file paths saying System32 doesn't mean anything. Normally, the first thing I do it check the registers, because they clearly show if it's a 32bit or 64bit process. Maybe I should just add a bug report header line to say whether it's a 32bit or 64bit process.

Anyway... I'm not sure what's going on here, it looks very weird to me. Maybe the crashing thread tried to execute code in a DLL/BPL which was already unloaded, or something like that.

Can you reproduce this problem? Can the end user reproduce it?

Hello madschi,

we have not been able to reproduce this behaviour.
Will keep an eye open if it happens again.

Thanks!

Ok, one-time weird effects can happen, I usually ignore them unless they start to occur more frequently. The issue could potentially also be caused by some 3rd party software running on the same PC, e.g. some anti-virus software or whatever.
