@pcanal @vgvassilev Any thoughts? |
I am unaware of such issues but that does not mean there are no such issues. Since when do you see these reports? Unfortunately we don't have a lot of options even if that's a valid issue as the JIT ROOT uses was deprecated in recent versions of llvm. If that's a significant problem for CMSSW we can try to investigate further. cc: @hahnjo, @Axel-Naumann, @lhames |
That's during ROOT's startup, and our ASAN builds do not show this issue. Could this be due to a compiler bug, e.g. an ABI incompatibility with / without rtti? Where can I find this compiler (on cvmfs) so I can build ROOT myself and try to reproduce this? Just FYI, llvm hasn't touched this code since llvm9 as used by ROOT's current master, i.e. there is no bug fix to be backported. |
@Axel-Naumann , you can |
@Axel-Naumann gentle ping on this issue |
Thanks. How urgent is this? That's not mean to an excuse - we should have acted earlier - but we need to sequence a couple of items for the next few weeks, and I'd like to understand how urgent this is, or whether "May" is enough. |
I think it's not urgent, just something that needs to be fixed eventually. @smuzaffar and @makortel can correct me if I'm wrong. |
any update on this in the last year :) ? |
From CMSSW, the error is still present in the IBs. In the latest UBSAN IBs the unit test ApeTest and multiple relvals failed with this issue. |
Let's cc: @hahnjo if he has some insights. |
No. My understanding is that it's still ROOT 6.26 and LLVM 9. Back then we also compiled |
@iarspider , is this still happening? All relvals and unit tests for UBSAN are running fine |
cms-bot internal usage |
@cmsbuild please close |
Several unit tests in UBSAN failed to initialize ROOT (?). E.g, Alignment/TrackerAlignment
