--- 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 > use -Wpedantic (GCC itself doesn't) and enabling the warning in -Wall or > -Wextra would likely lead to lots of noise for code that converts between > object and function pointers (POSIX requires it to work). > > A warning implemented in a front end can also only detect questionable > conversions but not the actual writes, which is what the warning I'm working > on does (i.e., detect stores into read-only storage). so... you're suggesting a new flag, then?
