The 64-bit garbage collector reserves a 32 GB heap and will not expand it further. If you allocate more than 32 GB you'll run out of memory. Another possibility is a bug in AUTO_USE_GUARDS. -- 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.
