            Bug ID: 18084
           Summary: backtrace (..., 0) dumps core on x86
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org

backtrace (..., 0) dumps core on x86

The call 'backtrace (buffer, 0)' dumps core on the x86 platform.  It should
return 0.  This bug caused a bleeding-edge version of Emacs to crash, as
reported in <http://bugs.gnu.org/19959>.  Thomas Fitzsimmons's standalone test
case (from the Emacs bug report) is attached.
