I'm pretty sure it fails on any platform that uses the modern ABI (iOS and 64-bit Mac), but I can't find the bug report at the moment. (The problem is that the forwarding machinery is hand-written assembly, and nobody added hand-written exception unwind tables to match. With "zero-cost" exceptions, the unwinder cannot process a frame without its unwind tables.) -- Greg Parker gpar...@apple.com Runtime Wrangler _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
