--- Comment #4 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:8f25c39c454d7d3d323edf014a653649946352bd commit r10-6266-g8f25c39c454d7d3d323edf014a653649946352bd Author: Jason Merrill <ja...@redhat.com> Date: Sun Jan 26 22:19:47 2020 -0500 c++: Fix array of char typedef in template (PR90966). Since Martin Sebor's patch for PR 71625 to change braced array initializers to STRING_CST in some cases, we need to be ready for STRING_CST with types that are changed by tsubst. fold_convert doesn't know how to deal with STRING_CST, which is reasonable; we really shouldn't expect it to here. So let's handle STRING_CST separately. PR c++/90966 * pt.c (tsubst_copy) [STRING_CST]: Don't use fold_convert.
