Status: RESOLVED DUPLICATE of bug 996060

(Firefox :: Untriaged, defect)

Description

[Jim Michaels]

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:55.0) Gecko/20100101 Firefox/55.0
Build ID: 20170803103124

Steps to reproduce:

function toUpperCase(s) {
	if (typeof(s)!="string") {
		try {
			throw("oops");
		}
		catch(e) {
			console.log(e.stack);
		}
	}
	var s2 = "";
	var A = 'A'.charCodeAt(0),Z = 'Z'.charCodeAt(0),a = 'a'.charCodeAt(0),z = 'z'.charCodeAt(0),diff = A - a;
	for (var i = 0; i < s.length; i++) {
		if (s.charCodeAt(i) >= a && s.charCodeAt(i) <= z) {
			s2 += String.fromCharCode(s.charCodeAt(i) + diff);//subtract 32 from lower case 96 which makes upper case 64
		} else {
			s2 += s[i];
		}
	}
	return s2;
}//toUpperCase(s)
toUpperCase(null);


Actual results:

does not dump call stack.


Expected results:

should have dumped call stack.
