There is HUGE amount of JIT FPU changes in beta that breaks it and there is no way to only do partial merge, everything has changed. It is b1 to b3, b2 had not JIT changes. (They are also in git repository)

Another big problem is that no one knows what instruction, effective address or even if it is something total different. It even could be totally unrelated to FPU, it may be just a trigger for another bug!

EDIT: More details

Peter narrowed it down to b3, I did some more tests to narrow it down to FMUL (by disabling JIT compilation for opcode one by one) which makes no sense and one addressing mode which also makes no sense because every program that uses FPU would break...

Which probably means bug is somewhere else.. This _really_ needs short test code, not big demo!
