> The method CachedDateFormat::findMillisecondStart() was changed in rev 1559522 for LOG4CXX-420.
> Since then I experience sporadic crashes in the method CachedDateFormat::millisecondFormat(). Further investigation showed that the specified parameter 'buf' is sometimes undefined, so any try to write sporadically fails.
> I have a debugging session open with the crash at the time of this writing. The current log message is "Current spot Reichenspergerplatz - EBP at (3,13) of entry 582" and should be written to a ConsoleAppender. The current conversion pattern is "%d %p [%c] %m%n". The call stack at the crash is (sorry, german version of vc2008):
