Artifact 04b01cd2af164a91d9cc1de8ed4276a3eb9eebd1b1d952077c3e8ee87cab3ffe:

• File src/OFXMLAttribute.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: 3649) [annotate] [blame] [check-ins using]
