[New-bugs-announce] [issue15030] PyPycLoader can't read cached .pyc files

New submission from Ronan Lamy <ronan.lamy at gmail.com>:

PyPycLoader can't read or write .pyc files created by the core import machinery. I'm attaching a failing test case demonstrating the issue: if you import a .py file using standard mechanisms, thus creating a .pyc, and then (in a separate process, say) attempt to make use of that cached file with PyPycLoader, the import fails with 'ValueError: bad marshal data (unknown type code)'.

It looks like that there has been a change in the binary format of .pyc files but PyPycLoader wasn't updated.
