Hi Borek,
I'm not sure I understand what you tried to do in the code you sent -
especially with the deletion mutex. However, if I replace the line:
CONDITION_WAIT(deleteMutex, deleteCondition);
From your search function with
_LUCENE_THREAD_FUNC_RETURN(0);
The second block of code runs just fine. If I don't comment out the
first block, it seem to run indefinitely.
I'd say your code logic is incorrect. See how threading is done in
TestThreading.cpp. You may want to implement the searcher deletion from
the main thread managing the searcher threads instead of from the
searcher threads themselves.
I tested with the atomicthreads branch only.
Itamar.

Enclosed test reproduces the problem with master branch. Could anybody try it
with atomicthreads?

I'm trying to to write some simpe test which produces the problem now.
It (probably) happens if thread calling _search finishes after related
IndexSearcher is deleted

If you're sure this is not a race condition between your threads, try
the atomicthreads branch. We fixed several threading errors there.
Actually, if this resolves this issue, I might just go ahead and merge
it to master and wait no more...

I run the IndexSearcher::_search method from separate thread (different from
thread
where IndexSearcher is created and deleted).
When the thread finishes, I get exceptionin mutex_thread::lock() The reason is
_internal is already deleted (contains 0xdddddddd).
Any idea what could be wrong?
