I don't see anything immediately wrong with your code. But I don't
think it is complete, I assume that in the Lua program you have the
line:
require("wx")
The program should show the two frames, the program "hangs" in the
wxWidgets event loop until you close them by hand and then your
probandoLua function is called.
Can you debug it? What platform? Did you compile everything,
wxWidgets, wxLua, Lua, etc all on your system or are you using
somebody's else's binaries? You note that you had to change the Lua
from 5.1.4... but I'm not sure I understand what you mean by that. The
crash could be because you linked against different versions of Lua
perhaps?
