--- Comment #2 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- Related to/duplicate of pr87881/pr87945/pr87993. > Changed between 20181028 and 20181104 (ICE). Parameter inquiry has been introduced at revision r265729: before it gave the error Error: Unexpected '%' for nonderived-type variable 'a' at (1) IMO you should give Paul a chance to fix pr87881 before filing new PRs.
