[Valgrind-users] pthread_mutex_lock/trylock: mutex has invalid owner

[Shavian S. <sha...@ya...>]

Hi, 
 
I am running valgrind checked out and complied on Red
Hat AS 3.0: 

# more /etc/redhat-release
Red Hat Enterprise Linux AS release 3 (Taroon)
# uname -a
Linux evdev04 2.4.21-4.EL #4 Tue Mar 9 13:41:05 EST
2004 i686 i686 i386 GNU/Linux


The program I am running is a multithreaded C++
daemon. It used to run find under valgrind 2.0.0 , but
with the valgrind compiled from the sources (checkout
out 5/2), it looks like there are problems in
pthread_mutex_lock/trylock (and possibly in execvp()
??). I am not able to pinpoint what exactly the
problem is. The relevant log snippets are below:

Note that the same daemon works perfectly fine in
valgrind 2.0.0. 

Any one faced similar issues or know any workarounds ?
Can it be some compilation issue?

thanks for any help. 

Shavian.
