Artifact 5693aff4f5638a3c7820e4f380e1a02ba9460c235b4c494e82d23f2c32c809de:

• File src/exceptions/OFChangeFileOwnerFailedException.h — part of check-in [e1e7ffa903] at 2011-09-22 23:25:42 on branch trunk — Exceptions are now autoreleased.

  This is safe as an "exception loop" can't happen, since if allocating
  an exception fails, it throws an OFAllocFailedException which is
  preallocated and can always be thrown.

  So, the worst case would be that an autorelease of an exception fails,
  triggering an OFOutOfMemoryException for which there is no memory,
  resulting in an OFAllocFailedException to be thrown. (user: js, size: 2127) [annotate] [blame] [check-ins using]
