            Bug ID: 99667
           Summary: RFE: complain about uninitialized member variables in
                    constructor
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: analyzer
          Assignee: dmalcolm at gcc dot gnu.org
          Reporter: dmalcolm at gcc dot gnu.org
            Blocks: 97110
  Target Milestone: ---

The analyzer could warn about C++ constructors that don't fully initialize all
member variables.

See e.g. bug 99617 (found by cppcheck).

Related (but perhaps different) are *usages* of member variables in a
constructor before initialization; see e.g. bug 19808 (though this should
probably be a different RFE, as it's more difficult)

Clang's analyzer does something like this:
