On Windows there is occasionally a crash when Lua attempts a Longjmp because an error has been raised. Windows complains about misaligned or invalid stack.

The error does not occur on Linux or MAC OSX (Yosemite).

It appears that this crashes are happening because LLVM generated JIT code lacks information required by Windows for proper stack unwinding.

It seems the error occurs usually in Release Debug builds. Full Release builds or full Debug builds are probably ok.

From v0.11 building 32-bit binaries - these do not appear to suffer from the issue

Since LLVM 4.0 looks like Windows 64-bit support has improved. Keeping this issue open until more testing is done.
