Daniel Marjamäki 10ae551fef CheckBufferOverrun: Use portability warning for pointer arithmetic UB. It can be used by intention and usually works as intended. 2014-12-22 10:56:17 +01:00
Thomas Jarosch dca65ce3da Fix FP if sizeof is used without parentheses on struct members
Right now we only support checking basic pointer types.
Pointers inside structs are not supported yet.

Consider the tokens "foo@1 . bar@2",
Token::Match( "sizeof ( %varid% )" ) won't match it.
Token::Match( "sizeof %varid%" ) did match it -> FP.
