Any idea what is wrong with Blind Mind's JIT compiler? I don't recall making any changes to the bytecode that should break the the JIT compiler, though you will need to recompile the JIT compiler for the new AngelScript interface.
Have you contacted Blind Mind about the problem already? ThyReaper here on the forum is their lead develeper. .
I have the jit source files integrated directly into my Visual Studio project so I recompile after updates anyways. I'm not familiar with AngelScript's internals but the problem maybe linked to the object register, since asCContext::GetAddressOfReturnValue() returns a null pointer from it. I've submitted a issue on the Git repository.
