SUMMARY I tried to made a memcheck with dwarf5 from clang it doesn't work, so i tried with the new git version like 3.20 and it's now fixed. But I want to ask you when a maintenance release of 3.19 could come with this fix ? SOFTWARE/OS VERSIONS OS : Ubuntu 20:04 Clang 14.0.3 Valgrind 3.19.0
Normally we do releases every ~6 months, so next release should be Oct 2022. Note that the support for clang generated DWARF5 isn't complete yet, see https://bugs.kde.org/show_bug.cgi?id=452758#c46 Best is to configure clang to not generate DWARF5 by default for now, valgrind isn't the only tool that has problems with it.
I'm not sure if support is yet complete but 3.20 shipped with dwarf 5 support.
