Public bug reported: I believe 2.11.1-0ubuntu7.14 (Ubuntu 10.04) introduces a regression in `getaddrinfo`.
I'm using the test case from [Debian Bug #304022](https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=304022) (attached as "main.c"). Valgrind detects a leak (output below) that isn't detected if I'm downgrading to 2.11.1-0ubuntu7.13. Upgrading to 2.11.1-0ubuntu7.16 doesn't resolve this. However, I'm unable to reproduce on 2.19-0ubuntu6.3 (Ubuntu 14.04). (The host in the test case yields a NXDOMAIN, but this isn't significant; it seems 1 kB will be leaked per block in any case.) ==7== Memcheck, a memory error detector ==7== Copyright (C) 2002-2009, and GNU GPL'd, by Julian Seward et al. ==7== Using Valgrind-3.6.0.SVN-Debian and LibVEX; rerun with -h for copyright info ==7== Command: ./a.out ==7== ==7== ==7== HEAP SUMMARY: ==7== in use at exit: 1,024 bytes in 1 blocks ==7== total heap usage: 58 allocs, 57 frees, 9,893 bytes allocated ==7== ==7== 1,024 bytes in 1 blocks are definitely lost in loss record 1 of 1 ==7== at 0x4C274A8: malloc (vg_replace_malloc.c:236) ==7== by 0x4EE7EC6: gaih_inet (getaddrinfo.c:858) ==7== by 0x4EEA8F1: getaddrinfo (getaddrinfo.c:2425) ==7== by 0x400606: main (in /tmp/a.out) ==7== ==7== LEAK SUMMARY: ==7== definitely lost: 1,024 bytes in 1 blocks ==7== indirectly lost: 0 bytes in 0 blocks ==7== possibly lost: 0 bytes in 0 blocks ==7== still reachable: 0 bytes in 0 blocks ==7== suppressed: 0 bytes in 0 blocks ==7== ==7== For counts of detected and suppressed errors, rerun with: -v ==7== ERROR SUMMARY: 1 errors from 1 contexts (suppressed: 4 from 4) ** Affects: eglibc (Ubuntu) Importance: Undecided Status: New ** Attachment added: "Test case to reproduce" https://bugs.launchpad.net/bugs/1364584/+attachment/4193570/+files/main.c -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1364584 Title: `getaddrinfo` leaks memory To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/eglibc/+bug/1364584/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
