--- Comment #3 from Manuel López-Ibáñez <manu at gcc dot gnu.org> --- (In reply to DJ Delorie from comment #2) > Once found, we scan backwards through the array looking for #pragmas that > might affect the diagnostic. If we see one, that's what we use. If we see > a DK_POP code, we skip over the chunk of the array to the matching PUSH > ([i].option), i.e. it's as if those actions never happened. The problem is that those actions had an effect. In this testcase, the #pragma GCC diagnostic error "-Wswitch-enum" enables the corresponding warn_switch_enum (which was not enabled in the command-line). Skipping until the push does not disable it back.
