Hi all, I'm on Ubuntu 18.04, running R-4.0.0 which I compiled from source, and using valgrind I am always seeing the following message. Does anybody else see that? Is that a known false positive? Any ideas how to fix/suppress? Seems related to TRE, do I need to upgrade that?

It is known, with a known workaround, see e.g. https://www.stats.ox.ac.uk/pub/bdr/memtests/README.txt . Set suppressions in ~/.valgrindrc, e.g. the CRAN check machine has --suppressions=/data/blackswan/ripley/wcsrtombs.supp It is an issue in your OS (glibc), not TRE nor R.

Great, that works for me, thanks! If this is an issue with glibc, has it been reported to the glibc devs, and are they working on a fix?
