FWIW, the culprit is this infinite loop:

while {![regexp -nocase {[a-z]} [string index $wordlet $beginIndx]]} {
append nonWord [string index $wordlet $beginIndx]
incr beginIndx
}

Under the right conditions (such as a word beginning or ending with "-"
or "_"), $wordlet will be null. When wordlet is null, [string index
$wordlet $beginIndx] will be null for all values of $beginIndx, the
regexp will never match, and the loop will never terminate.
