    Inheriting constructors

    +

    Do not use inheriting constructors (n2540).

    +

    C++11 provides simple syntax allowing a class to inherit the constructors of a base class. Unfortunately there are a number of problems with the original specification, and C++17 contains significant revisions (p0136r1 opens with a list of 8 Core Issues). Since HotSpot doesn't support use of C++17, use of inherited constructors could run into those problems. Such uses might also change behavior in a future HotSpot update to use C++17 or later, potentially in subtle ways that could lead to hard to diagnose problems. Because of this, HotSpot code must not use inherited constructors.

    +

    Note that gcc7 provides the -fnew-inheriting-ctors option to use the p0136r1 semantics. This is enabled by default when using C++17 or later. It is also enabled by default for fabi-version=11 (introduced by gcc7) or higher when using C++11/14, as the change is considered a Defect Report that applies to those versions. Earlier versions of gcc don't have that option, and other supported compilers may not have anything similar.
