There are no likely regressions. [Original Bug Text] The debug symbols from libglib2.0-0-dbgsym and libgtk-3-0-dbgsym don't get properly picked up by valgrind in eoan for some reason. The symbols correctly work under gdb. There is an warning printed from valgrind 'debuginfo section duplicates a section in the main ELF file' Laney tried to rebuild without dh_dwz and it makes the warning go away and the symbol work. Downgrading valgrind to the disco version doesn't fix the issue. ** Tags removed: verification-needed verification-needed-eoan ** Tags added: verification-done verification-done-eoan -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848211 Title: [SRU] valgrind fails to use debug symbols from glib/gtk To manage notifications about this bug go to: https://bugs.launchpad.net/valgrind/+bug/1848211/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
