PSA: If you are C/C++ developer, use cppcheck

[Rahul Sundaram]

Hi

In the last few days, I have been running cppcheck on quite a few programs
including systemd, transmission, libvirt,  ndjbdns etc and cppcheck has
found real and potential bugs (null pointer dereferences, uninitialized
variables, memory & resource leaks etc) in each of them.  I have reported
the ones I found and several developers have already fixed the issues.   A
couple of examples

http://cgit.freedesktop.org/systemd/systemd/commit/?id=e985665d2d226cb42b52bfcad6fd5b1586ad57d7

https://github.com/pjps/ndjbdns/commit/ee4112a702e22d447d9cd7bd31b880eacfe59a5e

You might also consider add a build target for regular checks

That would be all.  Thanks

Rahul
