--- Comment #11 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Mark Eggleston <markeggles...@gcc.gnu.org>: https://gcc.gnu.org/g:4d2a56a0f7135469587feacef44cf00e08f71d09 commit r11-3866-g4d2a56a0f7135469587feacef44cf00e08f71d09 Author: Mark Eggleston <markeggles...@gcc.gnu.org> Date: Thu Jun 11 14:33:51 2020 +0100 Fortran : ICE in build_field PR95614 Local identifiers can not be the same as a module name. Original patch by Steve Kargl resulted in name clashes between common block names and local identifiers. A local identifier can be the same as a global identier if that identifier is not a module or a program. The original patch was modified to reject global identifiers that represent a module or a program. 2020-10-14 Steven G.
