Compiling with debug and assigning an invalid directory to --slave-load-tmpdir was crashing the slave due to the following assertion DBUG_ASSERT(! is_set() || can_overwrite_status). This assertion assumes that a thread can change its state once (i.e. ok,error, etc) before aborting, cleaning/resuming or completing its execution unless the overwrite flag (i.e. can_overwrite_status) is true. The Append_block_log_event::do_apply_event which is responsible for creating temporary file(s) was not cleaning the thread state. Thus a failure while trying to create a file in an invalid temporary directory was causing the crash. To fix the problem we check if the temporary directory is valid before starting the SQL Thread and reset the thread state before creating a file in Append_block_log_event::do_apply_event.
