[Bug fortran/95980] ICE in get_unique_type_string, at fortran/class.c:485
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95980 --- Comment #16 from G. Steinmetz --- Yeah, and other parts are sort of amazing too. Let me allow to cite the complete 4.2, item 2, points (1)-(10) : 2 A processor conforms to this document if: (1) it executes any standard-conforming program in a manner that fulfills the interpretations herein, subject to any limits that the processor may impose on the size and complexity of the program; (2) it contains the capability to detect and report the use within a submitted program unit of a form designated herein as obsolescent, insofar as such use can be detected by reference to the numbered syntax rules and constraints; (3) it contains the capability to detect and report the use within a submitted program unit of a form or relationship that is not permitted by the numbered syntax rules or constraints, including the deleted features described in Annex B; (4) it contains the capability to detect and report the use within a submitted program unit of an intrinsic type with a kind type parameter value not supported by the processor (7.4); (5) it contains the capability to detect and report the use within a submitted program unit of source form or characters not permitted by Clause 6; (6) it contains the capability to detect and report the use within a submitted program of name usage not consistent with the scope rules for names, labels, operators, and assignment symbols in Clause 19; (7) it contains the capability to detect and report the use within a submitted program unit of a non-standard intrinsic procedure (including one with the same name as a standard intrinsic procedure but with different requirements); (8) it contains the capability to detect and report the use within a submitted program unit of a non-standard intrinsic module; (9) it contains the capability to detect and report the use within a submitted program unit of a procedure from a standard intrinsic module, if the procedure is not defined by this document or the procedure has different requirements from those specified by this document; and (10) it contains the capability to detect and report the reason for rejecting a submitted program. Thanks !

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95980 --- Comment #14 from G. Steinmetz --- > ... and real programmers wrote fine Fortran programs. Yeah, optimal world. That's probably the reason why some "real" programs don't need test cases - or at most three, because they cover everything ;-) Nobody likes "stupid" bugs. Aren't "smart" bugs from "smart" codes of "smart" people the better ones ?-) Some may proclaim 80% as the new standard threshold. But is 80% of 20% enough, and is there a VAT ?-) Most people underestimate the effort for thorough testing - not by a factor of 2, but by a factor of X or L or more. But enough with irony and sarcasm. --- Even the standards changed, too. F2018 has the audacity to demand chapter 4.2, item 2. I would like to see gfortran at a level where an average or casual programmer will not encounter an ICE with things like a forgotten/wrong keyword, attribute or syntactical element. It's easy enough to think logically wrong, to be in a hurry and mess things up. A compiler could be a helper and guide. No one said it wouldn't be hard and it won't take long. Thanks to all bold and brave people that work hard on it.
