>Description:
After updating my system to the lastest sources every Posix Thread application
caused this error on termination:

tron@lyssa:~>python2.2 
Python 2.2.2 (#1, Jan 28 2003, 00:47:46) 
[GCC 2.95.3 20010315 (release) (NetBSD nb3)] on netbsd1
Type "help", "copyright", "credits" or "license" for more information.
>How-To-Repeat:
Upgrade to "libc" 12.96 and try to use a threaded application.

>Fix:
None provided.

 >>> ^D
 assertion "next != 0" failed: file "pthread_run.c", line 115, function "pthread__next"
 zsh: abort      python2.2
 
 tron@lyssa:~>glxgears 
 Xlib:  extension "GLX" missing on display "localhost:10.0".
 Error: couldn't get an RGB, Double-buffered visual
 assertion "next != 0" failed: file "pthread_run.c", line 115, function
 "pthread__next" zsh: abort      glxgears
 
 [The "Xlib:" error in this particular example is completely unrelated.]
 
 I could fix the problem by downgrading to "libc" 12.95.
