--- Comment #1 from Marshall Clow (home) <mclow.lists at gmail.com> ---
Your comparison function (compareStr) does not impose a strict weak ordering on
the strings. Hence the behavior of sort is undefined.

A reasonable discussion can be found here:
https://www.securecoding.cert.org/confluence/display/cplusplus/CTR57-CPP.+Provide+a+valid+ordering+predicate

but your fails two simple tests.
   comp(a, a) --> false
   comp(a, b) != comp(b, a)
