Coverity Defect Density: LibreOffice vs Average
We run LibreOffice through Coverity approximately once a week. According to Coverity's overview dashboard our current status is:
LibreOffice: 9,500,825 line of code and 0.13 defect density
Open Source Defect Density By Project Size
Note: Defect density is measured by the number of defects per 1,000 lines of code, identified by the Coverity platform. The numbers shown above are from our 2013 Coverity Scan Report, which analyzed 250 million lines of open source code.
Line of Code (LOC) Defect Density Less than 100,000 0.35 100,000 to 499,999 0.5 500,000 to 1 million 0.7 More than 1 million 0.65
So any crashes you might experience in 4.3 are either a figment of your imagination or a sad commentary on the limitations of static code analysis.
