Here's the trackback I get with Python 2.7.  Look's like something's assuming that POP_JUMP_IF_FALSE target of 65541 fits in 16 bits.


Python 2.7.2 (default, Jan 13 2012, 17:11:09) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> with open('small_with_error.py') as f:
...     contents = f.read()
... 
>>> import compiler
>>> compiler.compile(contents, '<string>', 'exec')
POP_JUMP_IF_FALSE 65541
114 5 256
