Debugging the following crash

To all the expert in the forum,

I am running a simple macro to convert .asc to .root file.
The macro is working properly, but on the last file to be precessed, I always get this error:

can you please help?

ROOT Release: 60800

Dear @Fabi ,

The stacktrace you report doesn’t contain anything helpful unfortunately. We need more information, such as:

  1. Minimal reproducer of your problem (including input files which you can share privately if you can’t upload here)
  2. How you installed ROOT
  3. Operating system
  4. C++ compiler

Cheers,
Vincenzo
