Chris,

That number should be the number of bytecodes plus the number of trailer bytes. This should get the right sized method:

copy _ (CompiledMethod newMethod: m endPC - m initialPC + 1 + 4 header: m header)

However, I wonder why go to all that trouble. Why not export the method source and recompile it on the other end? That would avoid some of the grungier details.

Cheers,
Bob
