Look also the noExplicitConstructor entries :


Currently, with Krazy static analyzer, i disable the warnings, and all
re-appear with cppcheck.

This is a tedious problem. Try to force a missing explicit constructor, as :



>From Face Management code, and you will see a lots of errors.

Typically, the right constructor choice is delegate to the compiler, and
the state at run time can be undefined. This is especially the case for
contructor with one argument or more than one but with 2nd, 3rd, etc...
using default values.

I already fixed some simple case, but it's the hell to apply fix
everywhere, and i'm sure that side effect are introduced without explicit
