W2 crashes because of unallocated PDG lists

[Juergen Reuter]

W2 crashes with a NAG runtime error with the attached input file and the following error messages:

Is this because of a problem in the code or wrong usage? I'd suppose the first point.

Test input file triggering the problem

[Juergen Reuter]

Thanks to Sebastian Schmidt for reporting this error.

Without running the process, I observe that this already contains the bug:

model = SM
alias lepton = e1:e2

-> 'lepton' is empty.

Omitting the 'model' command (which is redundant since SM is the default model), 'lepton' acquires the correct value. I'll check this.

[kilian]

Fixed in changeset [1321].

The command model = ... did not work when the current model was merely confirmed. Now this case is handled correctly (re-synchronizing all parameters).
