Thomas Jarosch bac1dfce86 Add test cases when sizeof is used on struct members 2014-12-22 09:59:34 +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.
