Guard Malloc doesn"t work



I'm experimenting with different profiling options that Xcode provides, but when I enabling Guard Malloc option in Diagnostics tab and trying to run, I'm getting this error with immediate crash:







dyld: could not load inserted library: /usr/lib/libgmalloc.dylib







And it is right, /usr/lib/ doesn't contain this library. I've located it in:







Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk/usr/lib/







So I've created link, and started Command Line Tool (just to be sure, because it apparently part of MacOS SDK), enabled Guard Malloc again but the problem remains.


I don't quite get where is a problem: does it new Xcode 4.3 inadvertence, problem with my system or planned decision by Apple to replace it with something else (maybe Instruments )?

Slow Android emulator

I have a 2.67 GHz Celeron processor, 1.21 GB of RAM on a x86 Windows XP Professional machine. My understanding is that the Android emulator should start fairly quickly on such a machine, but for me it does not. I have followed all instructions in setting up the IDE, SDKs, JDKs and such and have had some success in staring the emulator quickly but is very particulary. How can I, if possible, fix this problem?
