Root.exe: free(): invalid next size (fast)

adrian_sev · October 25, 2021, 10:23am

_ROOT Version: v6-20-08
_Platform: el7

Hi! So, while i know that the question is not directly related to root, it involves the reading of a root backtrace [1]… so, hoping that this is not too off-topic, can someone point to me where exactly it the breakage? it would help me have a starting point for looking at a code with which i’m not familiar…
the error happens only in grid with ~ 8%
Thanks a lot!

If I’m not mistaken, the error comes from

/cvmfs/alice.cern.ch/el6-x86_64/Packages/JAliEn-ROOT/0.6.3-6/lib/libJAliEnROOT.so(_ZN12TJClientFile14getDefaultPathEv+0xa7)[0x2ba24e6a5877]

But maybe @axel can advise what to look for

Axel · October 26, 2021, 9:08am

Indeed, _ZN12TJClientFile14getDefaultPathEv crashes and that’s code from Alice. Could you ask on their mailing list / forum, please?

Thanks a lot! i just needed an expert opinion on the point of the problem i will see what can i do
