Thanks for the links.
If I run with libgmalloc, it dies the same way, but seemingly much quicker: Program received signal EXC_BAD_ACCESS, Could not access memory. Reason: KERN_PROTECTION_FAILURE at address: 0x00000032 0x95a82688 in objc_msgSend () (gdb) where #0 0x95a82688 in objc_msgSend () #1 0x90894910 in processColor () #2 0x9089395b in CharAttr () #3 0x9088db34 in -[NSRTFReader attributedString] () #4 0x9070bc03 in _NSReadAttributedStringFromURLOrData () #5 0x90709943 in -[NSAttributedString(NSAttributedStringKitAdditions) initWithData:options:documentAttributes:error:] () #6 0x9088c542 in -[NSAttributedString(NSAttributedStringKitAdditions) initWithRTF:documentAttributes:] () I also found a posting with someone with the exact same problem: http://www.mail-archive.com/cocoa-dev@lists.apple.com/msg27895.html I'm not sure what else to try. I'd be inclined to jump to the conclusion of blaming Apple, if it wasn't that this API must be a very widely called one. ________________________________ From: Sean McBride <cwat...@cam.org> To: Chris Idou <idou...@yahoo.com>; cocoa-dev@lists.apple.com Sent: Tuesday, 31 March, 2009 2:43:18 PM Subject: Re: EXC_BAD_ACCESS and NSAttributedString driving me crazy Chris Idou (idou...@yahoo.com) on 2009-03-30 8:25 PM said: >I'm getting NSRTFDPboardType and NSRTFPboardType objects as NSData from >the pasteboard and I'm storing them in a core data XML repository and >getting them out again, and when necessary I'm converting them into >NSAttributedString with initWithRTF or initWithRTFD.
