[issue9880] Python 2.7 Won't Build: SystemError: unknown opcode

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

You can look at Python/compile.c (the ast-to-bytecode compiler), Python/peephole.c (the bytecode optimizer), Python/marshal.c (the on-disk bytecode serializer/unserialize).

First step could be to actually disable the optimizer (see PyCode_Optimize in peephole.c).
