https://gcc.gnu.org/bugzilla/show_bug.cgi?id=89630 --- Comment #8 from Jason Merrill --- Author: jason Date: Mon Mar 18 19:37:00 2019 New Revision: 269777 URL: https://gcc.gnu.org/viewcvs?rev=269777=gcc=rev Log: PR c++/89630 - ICE with dependent using-decl as template arg. Even though these two using-declarations have the same effect, they are not the same declaration, and we don't need to work to treat them as the same like we do for typedefs. If we did need to, we would need to handle them specially in iterative_hash_template_arg as well as here. * tree.c (cp_tree_equal): Always return false for USING_DECL.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=89630 Jakub Jelinek changed: What|Removed |Added CC|jakub at redhat dot com|jason at gcc dot gnu.org --- Comment #6 from Jakub Jelinek --- Seems like a latent issue before, with the added new ia32 builtins we end up with lookup_template_class_1 looking up in type_specializations something with hash 40565706 and have already an entry with the same tmpl and hash 3584195152 in the table, but both of these % 61 are 35 and so spec_hasher::equal is invoked. e1->args is full-name "class A<#‘using_decl’ not supported by dump_expr# >" no-binfo use_template=1 interface-unknown chain >> and e2->args is: full-name "class A<#‘using_decl’ not supported by dump_expr# >" no-binfo use_template=1 interface-unknown chain >> Both are itself their own canonical types and template_args_equal calls same_type_p which ICEs on these. Before my r269472 change, DECL_UID of the *->tmpl was different, so different hashes and we were lucky that those two weren't compared. Jason, any ideas?

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=89630 --- Comment #5 from Jakub Jelinek --- Ah, ok, I was trying -march=skylake-avx512, but not -mrtm, now I can reproduce. As this is not a bootstrapped compiler, it can't be miscompiled, so I bet all my patch changed is adding a few DECL_UIDs (for the new builtins) and thus changing exact DECL_UIDs used on the testcase.
