           Summary: Segmentation fault in MOV multiplexer
           Product: Libav
           Version: git HEAD
          Platform: X86
        OS/Version: Mac OS
            Status: NEW
          Severity: major
          Priority: Normal
         Component: libavformat
        AssignedTo: bugzilla at libav.org
        ReportedBy: tdskywalker at gmail.com


Mac OS X 10.7.3, x86_64
llvm_gcc 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.1.00)

avconv segfaults when using the MOV multiplexer.

git bisect points to http://git.libav.org/?p=libav.git;a=commit;h=39f5a54

Seems like the issue *may* be triggered by the presence of chapters in the
source.
