Daniel Marjamäki 57ec1aea91 Library: Don't rely on ast in isNotLibraryFunction since it's used in tokenizer 2015-01-31 10:24:10 +01:00
PKEuS 98e33a189f Enhanced CheckBufferOverrun:
- Fixed bug in library: manual and existing libraries use "size", but library.cpp reads "sizeof" as podtype attribute
- Fixed a couple of bugs in handling unknown size in checkbufferoverrun.cpp, get size from library if available.

Heinrich Schuchardt bd67db96f1 5505: FP: Array accessed out of bounds
CheckBufferOverrun::checkFunctionParameter alreacy considered usage of a
function parameter inside an if block as a special case.

With the patch the same is done for switch statements.

A test is added.
