Daniel Marjamäki 5d0d21d668 Fixed a false positive (memory leak)

Daniel Marjamäki ed98f1b367 Fixed #131 (Regression: leak reported by 1.27 is not reported by 1.29)
The leak will be reported as a definite bug again. Not just a possible bug.
cppcheck don't know if the execution path is possible, but it knows that if the execution path is taken the memory leak will be certain.
