Artifact 07bbff71b3ee946b3cb78f94a69ae9e6baa3433855f7e7fc22dede1a9c34cdc3:

• File src/OFMutableDictionary.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: 3216) [annotate] [blame] [check-ins using]
