Daniel Marjamäki b7ba49114c Fixed #485 (detect when code is checking for null after dereferencing) 2009-07-20 18:53:41 +02:00
Daniel Marjamäki 74699cab66 memory leak for struct member: made the checking more sensitive. Skip bail-out execution paths were the member is properly deallocated 2009-07-20 14:39:24 +02:00
Daniel Marjamäki ddaea3244d memleak: implemented simple checking for leaking struct members 2009-07-19 16:51:31 +02:00
Slava Semushin d961e4b5c1 test/testrunner.cpp: fixed exit code when count of fails tests equals to 256.
When 256 tests fails return code was 0 and it was wrong. Now exit code
may be only 0 or 1 and not show how many tests fails.

Thanks to aggro80@ for pointing to this!

Kimmo Varis 70db2562f4 Fix ticket #417 (Crashes in Windows because of invalid char value)
8-bit characters and UTF-8 characters are now converted to spaces. They can only appear in the code files in comments or string/char constants. So we cannot just ignore them as that would change length.

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.
