PKEuS 0488f45a5f Removed standalone check CheckOther::checkDoubleFree(), integrated (most of) the functionality into CheckLeakAutoVar. Added support for new/delete to checkLeakAutoVar. 2015-01-28 17:38:43 +01:00
Daniel Marjamäki 3285f85ebf Fixed #6460 (Library: better function/type matching) 2015-01-27 17:55:18 +01:00
Thomas Jarosch 58cb6cc116 Add new "style" check to catch redundant pointer operations
Doing "&*some_ptr_var" is redundant and might be the remainder
of a refactoring. Warnings for expanded macros are excluded though:
They are often used with and without pointers and
do something like this: "func(&(*macroarg))".

The new check is fully AST based and was given
strong false positive testing on a large code base.

strdupa() / strndupa() allocates memory on the stack using alloca().
This memory is freed automatically once the current function is left.
