** Description changed: [impact] under some circumstances, libjemalloc2 hangs on arm64 architecture. [test case] - the mariadb-10.1 autopkgtests, specifically when apt installing mariadb- - server-10.1, will hang. It's possible the apt install mariadb- - server-10.1 hangs outside the autopkgtests as well, but the test - regression is very reproducable, e.g.: + as noted in debian bug 918742: - http://autopkgtest.ubuntu.com/packages/m/mariadb-10.1/cosmic/arm64 - - note the failures for version 1:10.1.38-0ubuntu0.18.10.1 + > 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.
