Re: @autoreleasepool casuses seg fault on new install

[allynm]

Hello Alessandro,

The code I'm using was created originally by Tobias Lensing and is available
at http://blog.tlensing.org/2013/3/02/24/.

The version I'm posting is somewhat hacked up with comments.  Please excuse. 
It fails as soon as it hits the first @autoreleasepool.

If I do traditional NSAutoreleasePool  * pool, all is well.
