Artifact e32818754d67ac36edfd3a630e9f45840e9691ec79b11c8514c6c6f88a32c833:

• File src/exceptions/OFMemoryNotPartOfObjectException.m — 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: 1578) [annotate] [blame] [check-ins using]
