Original description

What steps will reproduce the problem?
This code:
void loop() {
String stringOne = "this";
for (int charNum = 0; charNum < stringOne.length(); charNum++) {
char thisChar = stringOne.charAt(charNum);
Serial.println("Character " + charNum + " of " + stringOne + " is " + thisChar);
}
}

can be fixed by casting charNum to a String.

What is the expected output? What do you see instead?
Expected:
String character functions:
Character 0 of this is t
Character 1 of this is h
Character 2 of this is i
Character 3 of this is s

Got:
StringCharacterFunctions.cpp: In function 'void loop()':
StringCharacterFunctions:25: error: invalid operands of types 'const char*' and 'const char [5]' to binary 'operator+'
