I tried to search for open source static analysis tools for C/C++ code
(https://en.wikipedia.org/wiki/List_of_tools_for_static_code_analysis) . 
I found one tool called cppcheck, which is very useful. If you are using
Ubuntu machine, you can install the "cppcheck" pkg and use the tool. 
Few minutes back, I started exploring the tool with Cairo source and found
some errors reported by the tool. 
Fixed them and sent the patch for review. 
Please check it.
