*** stack smashing detected ***: terminated

ROOT

Hello,

I’m running a macro analysis.C that takes the input file name and the number of files it was hadded from as input:

root ‘analysis.C+(“190607_L7_0_955.root”,955)’

This runs fine if I run it over a single file, but crashes when ran over the hadded file. The error message is the following:

*** stack smashing detected ***: terminated

I have gone through the files and they seem healthy, I have no idea what’s going on here, any clue?

Thanks!

Does analysis.C contain any C-style arrays: double Something[52]? If so, for the large file there’s at least one entry where the array size (52 in this example) is insufficient.

That was exactly the situation, thanks so much!
