--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
GCC 4.2 is ancient and no longer supported.
This is not "critical", it's your code that has a bug, not the compiler.
You don't use A::isABC in the program, so it's a poor testcase.
There are lots of existing PRs about this, e.g. PR 2972 and PR 42000 and PR
