root.exe ERROR: Visual with requested ID of 0x22 is unusable - will try default instead.
Xlib: request 12 length 28 would exceed buffer size.

*** Break *** segmentation violation

Dear Mai,

Please specify the version of ROOT (5.34.xx?) and the system where you run.
Also, did you build / install by yourself or downloaded/using a pre-build binary?

There is a meaning less pointer used at a certain point, but it may be very difficult to find the cause of that without any additional information about the context bringing to the problem. For example, are you observing the problem always with the same file, event?
