@phaller said:
The problem is due to a bug in the clean-up phase that generates dynamic calls to methods of structural types. Normally, this bug should be fixed by Gilles. Since he is currently in the hospital, I tried to find out what the problem is. It seems that the check done in callAsOperator is wrong. Basically, it checks whether getPrimitiveReplacementForStructuralCall isDefinedAt ad.symbol.name returns true which it does since there is a replacement defined for the & operator. The problem is that the check does not take into account that & might be a method of a structural type.

Fixed (possibly improvably) in r18301.
