This can be reproduced using the following scenario:

• xrdcp localfile root://localhost//tmp/remotefile
• on the server side put a breakpoint in XrdOfsFile::write (1005)
• this will ensure that the file will be reopened (FileStateHandler::ReOpenFileAtServer)
• this in turn creates an OpenHandler object (FileStateHandler:1452) that is not synchronized (the userHandler is null)
• if the OpenHandler and the write operation timeout at the same time (this can be enforced using set in gdb) the FileStateHandler object is destroyed but concurrently the OpenHandler object is trying to call a method (XrdCl::FileStateHandler::OnOpen) on this object
