>Description:
An assertion failed in pthread while I was packaging
gnome-terminal-2.4.2.  gnome-terminal tests all possible charsets
using iconv to figure out which ones are available.  After trying
about 30 charsets, iconv_close() dumps core due to assertion failure
in pthread codes.

A *streamlined* version of gnome-terminal is attached below.  It
iterates over 32 charsets, calling iconv_open() and iconv_close() for
each.

Output::

BEGIN===================================================================
... (OK for 27 charsets)

DEBUG: testing charset GB18030.
DEBUG: Available
assertion "next != 0" failed: file "/usr/src/lib/libpthread/pthread_run.c", line 123, function "pthread__next"
Abort (core dumped)
END=====================================================================

I compiled this with the following command.

  cc -pthread -o terminal terminal.c

Without '-pthread', it runs well.  The assertion failure happens only
when '-pthread' is given.  I'm running one-month old -current (1.6ZG)
on i386.

>How-To-Repeat:
Compile the following program with '-pthread' option and run it.

terminal.c =============================================================
#include <stdio.h>
#include <iconv.h>

const int N_CHARSETS = 32;

static char *charsets[] = {
