XCode GCC-4.0 vs 4.2

Question

I have just changed a compiler option from 4.0 to 4.2.

Now I get an error:

jump to case label crosses initialization of 'const char* selectorName'

It works fine in 4.0

Any ideas?

Just a guess - you declare variable (probably const char*) inside 1 of your switch-case statements - you should wrap that case in {} to fix that.

// error
case 1:
   const char* a = ... 
   break; 

// OK
case 1:{
   const char* a = ... 
}
   break;
