RE: threads problems in RedHat9몗 媵

Maxim,

I had a similar problem - the destructors associated with thread
specific storage are not called in the RH 9 pthread library either.

You can work around this by linking against the pthread and libc
libraries in /lib or /lib/i686, which seem to work. Unfortunately, the
only way I could do this was to change the perms on the libraries in
/lib/tls so that the linker couldn't read them.

Regards

Tom

Hi there,

It seems to me that pthread_cleanup_(pop|push) routines are broken in
RH9. My multithreaded application works well only if I comment out all 
'pthread_cleanup_' strings in my program.
In most cases using pthread_cleanup_ routines lead to:
(gdb bt):
#1  0x4002fea9 in __pthread_cleanup_upto () from
/lib/tls/libpthread.so.0 #2  0x42027431 in _longjmp_unwind () from
/lib/tls/libc.so.6 #3  0x4202739c in siglongjmp () from
/lib/tls/libc.so.6 #4  0x4002ce62 in pthread_exit () from
/lib/tls/libpthread.so.0

Segmentation fault at exiting from thread.
There is any fix for it? Or something was changed in RH9 about 
pthread_cleanup_ routines?

Thanks in advice for any explanation.
Maxim.
