This needs the code from the git repository. The beta2 release
doesn't include this functionality.

And as doc/api.html and src/lj_err.c indicates it only works for
Windows x64, POSIX/x64 and (with some effort) for POSIX/x86. It
does not and will not work with Windows x86 due to the SEH
software patent.

This code works fine here with an out-of-the-box build of LuaJIT
on Windows/x64. Currently you need to compile your own C++ code
with /EHa. Apparently MSVC doesn't call C++ destructors for
foreign exceptions unless you use this flag. This is unfortunate,
but there's no easy workaround.
