Barry Revzin <barry.revzin at gmail dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |barry.revzin at gmail dot com --- Comment #3 from Barry Revzin <barry.revzin at gmail dot com> --- Shorter reproduction: struct S { S(int); }; S s{.why = 42}; This still compiles on trunk, even with all warnings and -pedantic. Made for a very difficult-to-track down bug, since designated initializers are a really nice way of mocking out named parameters (except when it's suddenly not).
