Static Analysis Report

kumararajas

Hello,

I ran the static analysis tool on my code. Since my code includes Qt libraries, it also analyses the header files. Tool has caught couple of warnings from the Qt sources.
I am using Qt 4.8.
Any thoughts if these are harmful? Should I need to get them fixed? if yes, how?

CL.MLK.ASSIGN: Possible memory leak in class 'QDebug'. Dynamic memory stored in 'stream' can be lost. : C and C++ : qdebug.h : Warning (3) : Analyze : Local
CWARN.BITOP.SIZE: Operands in a bitwise operation have different size : C and C++ : qglobal.h : Review (4) : Analyze : Local
CWARN.BITOP.SIZE: Operands in a bitwise operation have different size : C and C++ : qglobal.h : Review (4) : Analyze : Local
CWARN.MEM.NONPOD: Memory manipulation routine 'memcpy' is applied to a non-POD object : C and C++ : qvector.h : Review (4) : Analyze : Local
CWARN.MEM.NONPOD: Memory manipulation routine 'memcpy' is applied to a non-POD object : C and C++ : qlist.h : Review (4) : Analyze : Local

Thanks,
Kumara

Hi,

AFAIK:

stream is handled properly
sign extension must be taken into account when using the flag bitwise operator
IIRC, memcopy is used on classes that can be copied through it

As for fixes of Qt 4, AFAIK only security fixes will get in.
