Artifact 3d357d66d20b74475c5eb3b0841017126d59328e7f49da5bf48952e1cb92ecd8:

• File src/exceptions/OFUnsupportedProtocolException.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: 1540) [annotate] [blame] [check-ins using]
