Artifact 62f4043eb882b505583021072b7fb65d41306817bee3f843f70e57c44ccfac0a:

• File src/exceptions/OFEnumerationMutationException.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: 1480) [annotate] [blame] [check-ins using]
