I hadn’t, but changing this doesn’t help.  Debugging on the console isn’t too bad, although I am stuck at the moment while debugging one of the crashes I get running the testsuite on 10.12.

The two programs below both call DCSGetTermRangeInString, both work on 10.11, but the python version crashes on 10.12. Sadly enough it crashes in a secondary thread that’s doing some work for the DictionaryServices framework. I’m not yet sure why the python script causes a crash of the interpreter.

# Python
from DictionaryServices import DCSGetTermRangeInString

text = "the hello world program"
rng = DCSGetTermRangeInString(None, text, 5)
print(rng)
#end

// Objective-C
#import <CoreServices/CoreServices.h>
#import <Foundation/Foundation.h>

int main(void)
{
   CFRange rng;

   rng = DCSGetTermRangeInString(NULL, CFSTR("the hello world program"), 5);
   NSLog(@"%ld %ld", rng.location, rng.length);
   return 0;
}
// end
