Daniel Marjamäki b7c9a4ed8c Created a new class for detecting leaks (forgetting to free struct members) 2009-06-16 22:01:04 +02:00
Daniel Marjamäki ed98f1b367 Fixed (Regression: leak reported by 1.27 is not reported by 1.29)

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.
