lua_error() is "throwing a Lua error", because it actually unwinds
C stack frames.
Your problem sounds like an interaction with C++ RAII (automatic
destructors). Because this implicitly sets up SEH frames and those
get messed up when lua_error() unwinds the stack.
So check your code for uses of RAII. AFAIR Luabind has (or had?)
some of these internally, too.
[Anyway, Luabind has a high binding overhead and most of the CPU
time is probably spent there. LuaJIT is not going to help you with
that.]
