      Description

      If PosixFileMgr::fileClose() receives an invalid file handler or if its unable to close a file handler it will throw an exception. If this is done in an unwind of, for example, Janitor<BinInputStream> noone is around to catch that exception before the process is terminated. (Leaving a destructor with a throw during unwind is rewarded with termination of the process)

      This happens when variable "streamJanitor" goes out of scope in ReaderMgr::createReader(...)

      Callstack looks like this:

      This applies to WindowsFileMgr as well.
      If additional information is needed I'm happy to provide it.
