Bug ID: 96523
Summary: variable templates of constant types have incorrect
linkage
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: nathan at gcc dot gnu.org
Target Milestone: ---
Created attachment 49022

testcase part 1
non-template namespace-scope variables of constant type get internal linkage.
We're doing the same for template-variables, which is wrong. The attached two
sources should link and run w/o error. The executable returns 2 as the two
instantiations of CONST each has internal linkage.
devvm293:110>./cc1plus var-1_a.C -quiet
devvm293:111>./cc1plus var-1_b.C -quiet
devvm293:112>g++ var-1_*.s
devvm293:113>./a.out
(2)devvm293:114>
[basic.link]/3:
A name having namespace scope (6.4.6) has internal linkage if it is the name of
(3.1) — a variable, variable template, function, or function template that is
explicitly declared static; or
(3.2) — a non-template variable of non-volatile const-qualified type, unless
...
[Note: An instantiated variable template that has const-qualified type can have
external or module linkage,
even if not declared extern. — end note]
working on a fix, but would like confirmation of bug
