Interesting. The test case provided by Stefan does indeed crash
for me on Windows 7 Pro 64-bit, using Lua For Windows Version
5.1.4-45. The crash happens immediately on mouse-over inside the
frame. If the mouse happens to be sitting where the window opens,
then the crash is immediate. Otherwise, I can grab and drag any
of the borders or title without a crash.

The crash description reported by Windows is:

I notice with Dependency Walker against wx.dll that the only DLL
linked from a SxS assembly happens to be comctl32. I wonder if
there is some difference in the manifests provided for lua.exe
and wlua.exe that could relate.
