Hi Pepe,

This is a known (annoying) limitation of the automatic variable creation of CINT. There is no plan to fix this in the context of CINT (which is feature frozen).

Cheers,
Philippe.

Yes, it’s a long standing problem, I just got annoyed again today (well, I probably complained about it a long time ago but I forgot it).
Is this actually described somewhere?
I couldn’t find it either in http://root.cern.ch/viewvc/trunk/cint/doc/limitati.txt or in http://root.cern.ch/viewvc/trunk/cint/FAQ.txt

Hi,

It has now been added to root.cern.ch/viewvc/trunk/cint/doc/limitati.txt

Thanks,
Philippe.
