Is there a way to print a warning if you forget to declare in ctor initialization list a member POD? I'm looking through docs and can't find anything. g++-4.4 here.

If you want to warn about code that uses the uninitialized value of the variable in its own initializer, use the -Winit-self option. These warnings occur for individual uninitialized elements of structure, union or array variables as well as for variables that are uninitialized as a whole.
Warn about uninitialized variables that are initialized with themselves. Note this option can only be used with the -Wuninitialized option. This warning is enabled by -Wall in C++. This option controls warnings when a declaration does not specify a type.
These functions changed semantics in GCC 4.4. Warn whenever a function parameter is assigned to, but otherwise unused (aside from its declaration). To suppress this warning use the unused attribute (see Variable Attributes ). This warning is also enabled by -Wunused together with -Wextra .
To help detect accidental misuses of such arrays GCC issues warnings unless it can prove that the use is safe. See Common Variable Attributes . Warn for cases where adding an attribute may be beneficial.
You can enable -Weffc++ to get a heap of ridiculous warnings, including every single non-ctor-initialized member.
To check for actual UB, use valgrind.

You can use the option -Wuninitialized (and also -Wall).
However, It only warns if the Uninitialized type is being used.
Also, Ofcourse you can use other softwares like Valgrind and Cppcheck to determine Uninitialized types.
