Daniel Marjamäki 5d0d21d668 Fixed a false positive (memory leak)
This false positive was first discovered in the VLC sourcecode. The TestMemoryLeakInFunction::simple11 test case is a simplified test code of that code.

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 #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.

Daniel Marjamäki af7c63155e Fixed #387 (Templates: template functions that return a pointer are not simplified correctly)
* Fixed so that the tokenizer handle variable declarations better when the variable is assigned the return value of a template function
 * Fixed so that the simplifyTemplates detect that a template function is used when its return value is taken
