Hi everyone,
I have been running a macro for a few weeks with no problems, slowly adding on to it and it stopped working at some point. I made another smaller macro to test (code at the bottom of this post) and it is also having the same issue. I will attach the error below the code. I have been able to pinpoint the line that is causing it to have the segmentation violation, that being the line:
‘’’
decay_tree->SetBranchAddress(“decayHashExtended”, &decayHashExtended);
‘’’
If I comment it out, it runs fine. I know the script can read both files, and it will print everything out, then have the segmentation violation. Because I am a new user, it will not let me post links to the files, what is the best way for me to post them? If anyone knows what is wrong and how to fix it, thank you in advance!
Alex
