ILC model crashing

[Eothred]

Currently on my laptop, the ILC model is crashing. I have found out that it is due to the line 'use, sequence=EFF1;' in the last init file, but no idea why. The script runs fine in Mad-X.

>>> from cern import cpymad
>>> ilc=cpymad.model('ilc')

Right, so I figured out this is due to commit r4092 in Mad-X, the new garbage collector by Laurent. Not sure what is going on though..
