I marked debian-bug 918742 as being the upstream for this, but technically that bug was against fakechroot and the only change was to disable the hanging test; however jemalloc2 in debian did fix this, and the changelog entry for the fix only mentions that debian bug.
** Summary changed: - libjemalloc2 hangs on arm64 in some cases + libjemalloc2 hangs when used with fakechroot in some cases ** Description changed: [impact] - under some circumstances, libjemalloc2 hangs on arm64 architecture. + under some circumstances, libjemalloc2 hangs when used with fakechroot [test case] as noted in debian bug 918742: > apt install libfakechroot libjemalloc2 > LD_PRELOAD="libjemalloc.so.2 libfakechroot.so" /bin/true > <hangs> [regression potential] this patch is already included in disco and later; regression potential should be low. Regressions would likely result in more/different hangs. [other info] this patch is already included in disco/eoan. In bionic and earlier, jemalloc does not hook the _Unwind_Backtrace function. This hook appears to be what introduces the problem, and jemalloc only starts hooking the function in cosmic. ** Bug watch added: Debian Bug tracker #918742 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=918742 ** Also affects: jemalloc (Debian) via https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=918742 Importance: Unknown Status: Unknown -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1826883 Title: libjemalloc2 hangs when used with fakechroot in some cases To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/jemalloc/+bug/1826883/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
