Alright, so I dug deeper into this issue, since the Open Dynamics
Engine is triggering this issue now (and it's the only 3D
physics/collision engine with a C API I can find)
Apparently, loading a C++ library compiled with msys g++ causes LuaJIT
to crash when the process exits, even after the DLL was unloaded (I
set a breakpoint in lj_cf_os_exit, it crashes when exit() gets
called), even if the only calls through the FFI are those to extern
"c" functions. A small C program that just loads then unloads the
library works fine.
Here's the example code I'm using:
I don't think this has to do specifically with C++ code however. SOIL,
which is what I was having issues with earlier, is written in C, yet
still causes crashes, so I'm not quite sure.
May you please take a look into this, Mr. Pall?
Thanks, Alex Parrill
