For lua itself, and all it's libraries -- from same version / distribution of LuaDist, shouldn't they all be using the same runtime ? Anyhow, I will try using the DependencyWalker as you suggested.

I have also started a download of MinGW, but so far it's been a pain with multiple broken downloads, and restarting the graphical installer, seems to restart the download from the very beginning, i.e. doesn't seem to have a notion of restart. Once that is setup, I'll run my test again in debugger.

have you checked the dll's and exe's in use to be using the same runtime? (MSVCRT) You can check individual files using DependencyWalker (an MS tool).

Especially when dealing with 'handles' this will quickly get you in trouble when mixing runtimes.

Thanks Ian. Yes, I am indeed on Windows.

Since I don't do (and never did) any native programming (C/C++) on Windows, I don't have the development environment (compiler, debugger) setup. I was hoping that the error-message would tell something that people familiar with it might have better clues than I do.

LuaDist is compiled with MinGW AFAIK, so I guess installing GDB should be sufficient. I'll give it a shot.

Run it in a debugger and it will tell you the location of the issue. I'm assuming you're on Windows?

Researching about that error message, I've found several probable causes, ranging from the Antivirus software interfering, to Data Execution Prevention feature.

I have tried to use the ProcessMonitor tool (which is apparently the closest one can get to an 'strace' equivalent on Windows), but the "lua" ProcessName doesn't seem to show up, and still can't figure out with certainty. Any clues or guidance ?

Moving over from LfW to LuaDist, I am struggling with a bit of a problem with the library luars232.dll. I get an "Invalid access to memory location "

Any ideas on what I could try ?
