--- Comment #5 from Jason Merrill <jason at gcc dot gnu.org> --- Author: jason Date: Tue Dec 17 21:46:11 2019 New Revision: 279472 URL: https://gcc.gnu.org/viewcvs?rev=279472&root=gcc&view=rev Log: PR c++/92576 - redeclaration of variable template. The variable templates patch way back when forgot to add handling here. The simplest answer seems to be recursing to the underlying declaration. * decl.c (redeclaration_error_message): Recurse for variable templates.
