Re: thread local storage support in libc

Hi Zoltan,

I have to admit, I do not know the root cause of this problem. It seems, that 
the runtime linker ld-2.3.2.so that gets installed in /lib64 has some symbols 
missing that are needed for some (all?) multithreading programs.
But, at least I have found a work around:

When I copied /lib64/tls/ld-2.3.2.so onto /lib64/ld-2.3.2.so then everything 
works.
BIG WARNING: you cannot simply copy the runtime linker in a running system. It 
is needed for every program you start (ignoring statically linked programs).

That is how I did it:
$ mv /lib64/ld-2.3.2.so /lib64/x-ld-2.3.2.so-x        # just to keep the 
original version
$ /lib64/tls/ld-2.3.2.so /bin/cp /lib64/tls/ld-2.3.2.so /lib64  # need to call 
cp explicitely using /lib64/tls/ld-2.3.2.so because the 
searched /lib64/ld-2.3.2.so is currently unavailable!

I hope, that we can solve this problem soon so that this ugly work around is 
no longer needed.

Regards,
Hans-Frieder
