Never mind. For whatever reason RangeError is now caught. Sorry 
for the noise.

How to catch RangeError in unittest?

[wjoe via Digitalmars-d-learn]

I have a function add(index, data) which throws RangeError if the 
index is invalid.


unittest { // is supposed to test that RangeError is thrown on a 
range violation
   assertThrown!RangeError(add(size_t.max, something)); //which 
doesn't work, the test is killed with core.exception.RangeError: 
Range violation


   // this kills the test, too: core.exception.RangeError: Range 
violation

   try {
 add(size_t.max, something);
 assert(false, "Expecting RangeError");
   } catch (RangeError) {}
}

Just for clarification, I do _not_ intend to catch RangeError 
outside of a unittest. What I want is that the test acknowledges 
the correctly thrown RangeError and gracefully reports success.



What are my options?
