The iostreams functions contains a catch-all clause which does not rethrow the exception. This is possible to expect but should really never happen in any code. The rules C++ experts developed state that catch-all cases must rethrow. If not then strange things can happen since one doesn't always know exactly what exceptions are thrown. Simple patch for sync functions attached." Bugs new To Be Determined iostreams Boost Development Trunk Problem iostreams pthreads exceptions
