           Summary: re_match_2, re_search_internal, etc. infloop on
                    persistent failing calloc
           Product: glibc
           Version: 2.13
            Status: NEW
          Severity: normal
          Priority: P2
         Component: regex
        AssignedTo: drepper.fsp@gmail.com
        ReportedBy: jim@meyering.net


Ignoring a failing calloc in build_trtable causes its caller, transit_state to
get stuck in an infinite loop.

Patch below.

Adjusted git patch to have a sensible subject (i.e., not matching the bare BZ
number of the first line of ChangeLog entry).
