             Bug #: 14562
           Summary: threaded programs with x32 abi randomly crash with
                    arena.c:661: heap_trim: Assertion `p->size == (0|0x1)'
                    failed
           Product: glibc
           Version: 2.16
               URL: https://bugs.gentoo.org/show_bug.cgi?id=394175
            Status: NEW
          Severity: normal
          Priority: P2
         Component: nptl
        AssignedTo: unassigned@sourceware.org
        ReportedBy: vapier@gentoo.org
                CC: drepper.fsp@gmail.com
    Classification: Unclassified


test case:
- use glibc-2.16 with x32 abi
- get a bunch of files (like ~150; perl man pages are a sample input)
- run `bzip2 -k <files>`
- run `pbzip2 -k -f <files> -p4`

see crash:
pbzip2: arena.c:661: heap_trim: Assertion `p->size == (0|0x1)' failed.

this has happened with a other threaded programs (git & squashfs); see gentoo
bug for some more details
