- by Aleksejs

File main.m is simple as possible:
#import <UIKit/UIKit.h>
int main(int argc, char *argv[]) {
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
int retVal = UIApplicationMain(argc, argv, nil, nil); // line 14
[pool release];
return retVal;
}
What my cause the app to crash?
