Processing the object file with ld strips away debug information for the main() function, resulting in the debugger not being able to break on specific lines of the function. It also causes issues when externing sybols in main's object file. We revert back to the approach of using the strings in-line in the object file (which is why we keep the name the same length, 'qtmn').
