Summary:                    Weird linking behaviour
Description: 
I have an application that is linked dynamically to a shared lib, which
itself uses pthreads and is dynamically linked to the pthreads lib.

When a worker thread is created and started, the thread function is
called. But the main thread (which created the worker thread) never is
scheduled/run again! If the worker thread contains an infinitive loop, it
runs forever. If it exits (by using return) the whole process doesn't do
anything anymore.. It is blocked.

IF I link the pthreads lib to the application as well, the same code works
fine. The main thread and the worker thread are both scheduled as
expected.

Hi,
as Mike already asked, please provide us with a test case.

Hello,
I'm just thinking to a problem caused by wrong libgcc_so.
I suggest you to build ld.so with LD_DEBUG options enabled and run the
test case
again. We should be able to track the order and where the ld.so is
looking
for shared libraries.
