  • File src/OFDataArray.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: 12126) [annotate] [blame] [check-ins using]
