Great!

I can't reproduce this. I compile and run this program:
#import <objc/runtime.h>
#include <stdio.h>
int main(void)
{
Method m = class_getInstanceMethod(objc_getClass("Object"), @selector
(free));
printf("Name: %s\n", sel_getName(method_getName(m)));
printf("Types: %s\n", method_getTypeEncoding(m));
printf("IMP: %d\n", method_getImplementation(m));
return 0;
}
And I get:
Name: free
Types: @8...@0:4
IMP: 675116096
The runtime here is just getting the value set by the compiler, so if
this is (unsigned int)-1 for you then it may be a compiler bug. What
compiler are you using?

Fixed, thank you. See r29214 for libobjc2 and r5724 for
ObjectiveC2.framework.

Yes, definitely. Bug reports are always welcome, than you.
