BUG OF THE MONTH | Free of Pointer not at Start of Buffer V726 An attempt to free memory containing the ‘wbuf’ array by using the ‘free’ function. This is incorrect as ‘wbuf’ was created on stack. log.cpp 216 template<typename T> static ALWAYS_INLINE void FormatLogMessageAndPrintW(....) { .... wchar_t wbuf[512]; wchar_t* wmessage_buf = wbuf; .... if (wmessage_buf != wbuf) { std::free(wbuf); } if (message_buf != buf) { std::free(message_buf); } .... } Here the analyzer detected code with an error. In this code fragment, we see an attempt to delete an ..read more

BUG OF THE MONTH | An always-false expression V547 Expression ‘h == 0’ is always false. jpegcodec.cpp 252 BLResult blJpegDecoderImplProcessMarker(....) noexcept { uint32_t h = blMemReadU16uBE(p + 1); // ....if (h == 0) return blTraceError(BL_ERROR_JPEG_UNSUPPORTED_FEATURE); // .... impl->delayedHeight = (h == 0); // <=// .... } In this code fragment, the result of the blMemReadU16uBE function call is assigned to the h variable. Then if the h == 0 check is true, we exit from the function’s body. During initialization impl->delayedH ..read more

BUG OF THE MONTH | Assignment to Variable without Use private void Draw(Rect windowRect) { var rect = new Rect(....); .... if (m_NumFilteredVariants > 0) { .... if (m_NumFilteredVariants > maxFilteredLength) { GUI.Label(....); rect.y += rect.height; } } else { GUI.Label(rect, "No variants with these keywords"); rect.y += rect.height; // <= } rect.y = windowRect.height - kMargin - kSpaceHeight – EditorGUI.kSingleLineHeight; // <= .... } V3008 The ‘rect ..read more

BUG OF THE MONTH | Unnecessary actions V3107 Identical expression ‘power’ to the left and to the right of compound assignment. RelayComponent.cs 150 public override void ReceivePowerProbeSignal(Connection connection, Item source, float power) { .... if (power < 0.0f) { .... } else { if (connection.IsOutput || powerOut == null) { return; } if (currPowerConsumption - power < -MaxPower) { power += MaxPower + (currPowerConsumption - power); } } } The programmer is trying to add MaxPower,  ..read more

BUG OF THE MONTH | Incorrect Calculation V1064 The ‘1’ operand of integer division is less than the ‘100000’ one. The result will always be zero. OgreAutoParamDataSource.cpp 1094 typedef Vector<4, Real> Vector4; const Vector4& AutoParamDataSource::getShadowSceneDepthRange(size_t index) const { static Vector4 dummy(0, 100000, 100000, 1/100000); // .... } Here the dummy vector should store floating point numbers. In this case, the constructor receives 4 arguments of the float type. However, there are integer values to the left and right of the divisi ..read more
