REVAN Crash (segmentation violation)

[mikemoss3]

Hello,

I don't have much experience with ROOT error messages, so I hope you can help me figure this one out.

When running REVAN I successfully run "Start Event Reconstruction", but when I attempt to use the "Energy spectrum Before/After analysis" in the "Analysis" menu, but I receive an error dealing with memory issues (I believe). I will post the full error message displayed at the end of this post.

This happens for multiple different source/geometry files that I attempt this on.

Error Message upon execution:

Warning in <TROOT::Append>: Replacing existing TH1: InitialEnergySpectrum (Potential memory leak).

 *** Break *** segmentation violation

Hi Mike,

Can you email me your geometry, a small sim file which causes the crash, and your revan configuration file? Then I can debug.

Best,
Andreas

[mikemoss3]

Ok, I have sent the needed files.

Best,
Mike

[zoglauer]

Fixed.
