As for the "example" .pyc just create an empty 0 byte .py file and compile it,
that is the same .pyc that is created in my system (instead in my case the .py
is not empty).
Just so people don't have to trace the code like I did, here is the traceback
of the primary issue. Remember that my hypothesis is that fopen returns an FILE
stream, that returns EOF on the first get because of an I/O error, not because
the file is empty:
--> GETC is called, and gets EOF on the first try, and thus
Py_UniversalNewlineFgets returns NULL

-> Now load_source_module has an empty AST which will get compiled to an empty
code module
-> this code is optmized so we don't see the parse_source_module call
here, but write_compiled_module will be called afterwards with the empty
AST tree instead of aborting...
