Description

The following code extract causes a crash within a multi threaded environment
LevelPtr Level::getFatal() {
static LevelPtr level(new Level(Level::FATAL_INT, LOG4CXX_STR("FATAL"), 0));
return Fatallevel;
}

File level.cpp file. If two threads call this simultaneously or any of the other Level::getXXXX functions, the second thread may get a null pointer returned if the first thread is still constructing the static LevelPtr level object.
