             Bug #: 13725
           Summary: __gconv_lock missing pthread_atfork handler
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
        AssignedTo: unassigned@sourceware.org
        ReportedBy: wingo@pobox.com
                CC: drepper.fsp@gmail.com
    Classification: Unclassified


Consider a multithreaded program that forks while another thread is doing an
iconv_open.  This program might deadlock on the __gconv_lock, for obvious
reasons.

I realize that POSIX does not define the behavior of a program that calls
non-async-signal-safe functions after a fork.  However glibc does install
thread_atfork handlers for a number of other subsystems, including malloc, a
non-async-signal-safe call.

Suggestion: add a thread_atfork handler for the __gconv_lock.
