Problems with MLM matching

Hi,

This does not seems to be a simple problem.
THere is an issue with a patch on the computation of the renormalisation scale
in this case. It will likely take a bit of time before being able to study what's going on here.

Cheers,

Ollivier

I have create a bug from this question such that I was able to attach a file (in this case a patch)
