Segmentation problem, but not knowing where

Hello, the simulation compile but there is a problem when running.
Unfortunately, the gdb only says:

Program received signal SIGSEGV, Segmentation fault.

Then I don’t know in my code where is the problem. Is there other way to know the code producing this problem?

If you’re using GDB, as you say, then type “bt” and you’ll get the traceback of all the calls. It should be fairly self-explanatory if you’re familiar with C++ and your own code.

Hi @mkelsey mkelsey, the problem is that the error that I quoted in my previous message is the result of the “bt” command! That’s because I don’t understand the error…i.e. instead to give an error in my code, it gives error in the G4LocicalVolume!

Solved myself.
