Dear colleagues,

while filling histograms I’got the message about the crash. What can be the reason?

Thank you in advance,

 *** Break *** segmentation violation

There was a crash.
This is the entire stack trace of all threads:

We would need a small reproducer to help you.

Do you mean the program?
It was working well at the statistics below 10000000 events. But after increasing the statistics to 100000000 it crashed at 38000000.

I’m sorry. Seems I found the problem myself - it was in dimentionality array that I filled in. It was too small. Thank you
