Usually when I face this kind of prob, the most likely reason there is some uninitialized variable that you are using later. Uninitialized variable act differently depending on compiler.

if (sz(ss) > 2 && ss.find(nounM, siz - 3) != -1) [line 72]
siz = sz(ss) - 1 [line 65]

So, if ss = "etr" then siz will be 2 and siz - 3 will be -1. Change line 65 to siz = sz(ss) and fix similar errors.

      UPD: I was wrong again. But now I could debug this "solution" and hope to give exact answer in a few minutes.

      UPD more: I fear you need to specify what exactly compiler do you use with eclipse. I could not find out which compiler could ever give "yes" for "etr" testcase - and so I could not reproduce your question.

        I use mingw GCC
        please tell me what's the compiler you use to make local test like judge test 
        thanks :)
