It gives an error when compiled as 32-bit and ran on a 32-bit OS

Ah, yes, I remember in 2018 when I wrote the following:

+GoBonnieGo may have difficulty running on 32-bit systems; int and int64 were used interchangeably in the code.

I'm curious: what's the use case? As far as I know, you're the first to attempt running GoBonnieGo on a 32-bit system.

When I have time, I can look at the code & try to make fix it, but if you want it done faster you might try a pull request.

My use case is to test a UDFS driver under both 32 and 64-bit OSes for bugs so they can be fixed. Maybe you could tell me how to fix the original Bonnie++ so that a crash no longer happens and it is able to finish running its benchmarks.

By the way, thanks for the most excellent bug-dump info.

[Zero3K]

That's the crash which happens when running a compiled exe of the original version (if you know C++, maybe you could offer the fix as a PR to my mirror, which is at https://github.com/Zero3K/bonnie). I got the backtrace by adding the proper switches to the Makefile.nt and using WinDbg's !gflag +soe and then running Bonnie++.

Maybe you could get it to compile properly under Visual Studio 2019.
