--- Comment #9 from Martin Sebor <msebor at gcc dot gnu.org> ---
pr90404 is somewhat related to this: it requests a new warning option to flag
attempts to modify a const object of any type/kind. In my prototype
implementation of it that I hope to submit for GCC 11 I call the option
-Wwrite-const. It's implemented in the middle end so it detects all such
attempts, including for instance things like '*strchr("x", 'x') = 0', and
avoids triggering on provably unreachable code. It's just as capable as other
late warnings, but, of course, also subject to just as many false positives and
negatives as they are.
