EXE BAD ACCESS in line 14 in main.m after I type randomly when program launches?

I got this weird crash EXE_BAD_ACCESS error when I typed randomly by keyboard in freshly new View Based Application project in Xcode 4.1 and iOS SDK 4.3. When I press run after I created a View Based Application Project, a blank screen with come. And when I start to press keys from keyboard two to five letters ,it crashes on main.m file line no. 14.

9  #import "UIKit/UIKit.h"
10 
11 int main(int argc, char *argv[]) {
12    
13    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
14    int retVal = UIAp开发者_开发知识库plicationMain(argc, argv, nil, nil);
15    [pool release];
16    return retVal;
17  }

Please help, I want to know what's going on. Any links, related posts would be helpful.

Thanks.

See this thread. It is of course a bug with Xcode 4.1 build: 4B103. https://github.com/futuretap/InAppSettingsKit/issues/75#issuecomment-2343312
