[Valgrind-users] Problem with pthread_once

[David J. <dj...@ho...>]

While running an application on RH 9 using valgrind 1.9.6, I get the 
following messages

==3029==
valgrind's libpthread.so: pthread_once: Looks like your program's init 
routine calls back to pthread_once() ?!


==3029==
valgrind's libpthread.so: pthread_once: Looks like your program's init 
routine calls back to pthread_once() ?!

and the application is terminated.  Using gdb (without valgrind) I find 
that there are many calls to pthread_once, mainly from dlopen and dlsym, 
before the point where valgrind complains.

Any idea about how to track down the offending call, or the likely cause of 
the problem?
