Bug#564274: g++-4.4: Program is compiling by g++, even there is a bad conversion

[Sławomir Domagała <godlark@gmail.com>]

Package: g++-4.4
Version: 4.4.2-8
Severity: normal

I can't make shorter source code, where is this error, thus I've got all source code from my programme, but I've written which lines is the error.

Line from 156 to 161 in engine.cpp:

SingleWord sword;
//definition class SingleWord is in file "SingleWord.h"
for(ushort i = 0; i < number_words; i++) {
      atime = time(NULL);
      sword = courses[activ_course]->getSingleWord(swords[i]);
	//courses is vector<Kurs>, definition class Kurs in file "kurs.hpp"
      sword.setSpelling("cat");

But definition function getSingleWord(swords[i]) is:
SingleWord const* Kurs::getSingleWord(ushort number) const
{
        if(number >= qAllSingleWords)throw Error::newError(Error::BAD_ARGUMENT, "", __LINE__, __FILE__);
        return number < wordl1.size() ? wordl1[number] : wordl2[number-wordl1.size()];
}

The source code is compiling with no errors: "g++-4.4 -pedantic main.cpp engine.cpp nakladka2.cpp kurs.cpp SingleWord.cpp RegisterOfErrors.cpp -lboost_regex-mt -o main.e"
