Jason Merrill <jason at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jason at gcc dot gnu.org --- Comment #6 from Jason Merrill <jason at gcc dot gnu.org> --- (In reply to Harald van Dijk from comment #5) > (In reply to Jakub Jelinek from comment #4) > > Just use -pedantic-errors if you want strict language conformance? > > -std=* -pedantic is supposed to be enough to get GCC to conform to the > specified standard (the standards pretty much never require an error) Yes, and it does: it gives a diagnostic about a VLA (because the bound is not a constant expression). The standard doesn't require particular wording in the diagnostic. > but > anyway, even with -std=c++14 -pedantic-errors, no message at all is given > for the program in my earlier comment. I don't see the syntax error in your earlier comment, S()=1 is a C++14 constant expression.
