Re: FFC errors

 

I tried to reproduce it by altering the __init__ files in cache and various other things, without success. Will eave things as they are next time it happens, I really cannot understand how this can happen after having a closer look at jit.py.

I tried to reproduced this but I couldn't. It should be easy to fix if
I can get my hands on it.
