--- Comment #3 from Nathan Sidwell <nathan at gcc dot gnu.org> --- The modules branch identifies itself as: gcc version 10.0.1 20200211 (experimental) [devel/c++-modules fe76dae46c6:20200212-0942] (GCC) I added the branch name to the [...] piece last week. Its ICE and --help output also says: For bug reporting instructions, please see: <https://gcc.gnu.org/wiki/cxx-modules#Bugs>. I would like to keep the actual version number tracking the (frequent) merges from trunk, rather than invent something else. I guess the '(experimental)' part could say something else. (modules)? Though I don't know what scripts out there might barf on that. As to Chris's report -- this is a known defect mentioned on the modules wiki page -- concepts support is incomplete. I suspect on trunk I should add modules-specific smarts to the parser error message route, so it can say something clueful.
