Subject: [Bug middle-end/95485] missing warning writing into function text
Date: Tue, 04 Jan 2022 06:51:55 +0000 [thread overview]
Message-ID: <bug-95485-4-MMFPONver2@http.gcc.gnu.org/bugzilla/> (raw)
In-Reply-To: <bug-95485-4@http.gcc.gnu.org/bugzilla/>

--- Comment #4 from Eric Gallager <egallager at gcc dot gnu.org> ---
(In reply to Martin Sebor from comment #3)
> Ah, yes, -Wpedantic does detect the invalid conversion. But few projects

so... you're suggesting a new flag, then?
