Filling a tree: SIGSEGV

[bomben]

Hi all,
in a read and fill compiled program, I keep getting this kind of crash:

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread -1249487152 (LWP 14068)]
0xb6ff39ff in TKey::Create ()
from /home/bomben/work/root-520/root/lib/libRIO.so
(gdb) where

#4 0xb6613867 in TTree::Fill ()
from /home/bomben/work/root-520/root/lib/libTree.so

I need to run my program under gdb to get some info, and still I can’t figure out what’s wrong…

Does anyone have an idea how to investigate this?

I’m using root 5.20 on a linux machine.

Regards,
Marco

Hi,

Your best bet is to use a debug version of ROOT and use gdb on the executable named root.exe:gdb root.exe
