[Rivet] segfault while declaring arrays of histograms

[Raghav Kunnawalkam Elayavalli]

Hi David and Holger,

yeah ive used gdb long ago with root, but could you help me with using gdb with rivet now?

As it happens, im struggling with another crazy run-time seg fault (which ive had two of my colleagues look at without any success in debugging it) at the moment and would really appreciate any help.

Cheers
Raghav

Hi Raghav,

It looks like Holger found the typo. A few tips:
1. C++ is multi-paradigm, but I tend to prefer using C++ data structures over C since they tend to throw meaningful exceptions where C just blows up
2. Gdb is your friend when it comes to debugging segfaults

Shameless plug for a resource I wrote:
www.phy.duke.edu/~dmb60/the-guide<http://www.phy.duke.edu/~dmb60/the-guide>

There are links to lots of HEP software resources and, specific to you gdb, tutorials.

Good luck!

Hi Raghav,

that looks roughly correct to me, maybe this is the culprit:

++j  maybe?
