We’ll have to fix this in ROOT. There is nothing you can do to avoid this for the time being (beside not typing wrong names…)

Cheers, Bertrand.

A comment:

root [0] TFile *f = new TFile("J20.root",UPDATE);
input_line_9:2:26: error: use of undeclared identifier 'UPDATE'
 (new TFile(("J20.root", UPDATE)))

The ROOT will crash while I forget the double quotation marks “”.

Thank you!

Well, ok, thanks, but this is exactly the same issue… You can find thousands of examples, they will all make ROOT crash…
