Summary: While running, Xcode and Property List Editor constantly spam the console log with malloc error messages. This makes Console.app significantly less useful. On Tiger, I left Console running all the time, and I had it bounce in the Dock when a new console message appeared. This was quite useful for discovering problems and debugging. However, I run Xcode frequently, and since Xcode constantly spams the log, I no longer want to have Console bounce in the Doc. Steps to Reproduce: 1. Clean install Mac OS X 10.5.5 2. Clean install Xcode 3.1.1. 3 Launch Console. 4. Launch Xcode. 5. Do stuff with Xcode, like open and project and work. Expected Results: Xcode doesn't spam the console log. Actual Results: Xcode spams the console log. I see messages such as the following: 10/17/08 6:48:59 PM Xcode 955 com.apple.Libsystem.malloc Error Xcode(955,0xb0103000) malloc: free_garbage: garbage ptr = 0x299e450, has non-zero refcount = 1 10/17/08 6:48:59 PM Xcode 955 com.apple.Libsystem.malloc Error Xcode(955,0xb0103000) malloc: free_garbage: garbage ptr = 0x29a34b0, has non-zero refcount = 1 10/17/08 6:48:59 PM [0x0-0x96096].com.apple.Xcode 955 com.apple.console Notice Xcode(955,0xb0103000) malloc: free_garbage: garbage ptr = 0x299e450, has non-zero refcount = 1 10/17/08 6:48:59 PM [0x0-0x96096].com.apple.Xcode 955 com.apple.console Notice Xcode(955,0xb0103000) malloc: free_garbage: garbage ptr = 0x29a34b0, has non-zero refcount = 1 Regression: This problem did not occur with Mac OS X 10.4.11 and Xcode 2.5.
