Bug ID: 68437
Summary: [concepts] fold expression, pack expansion, and
deduced constraint requirement
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: lucdanton at free dot fr

Minimal testcase
This is using g++-trunk (GCC) 6.0.0 20151103 (experimental). Attached testcase
is as minimal as I could manage. If I change the fold expression in the
requirement to a 'manual', compile-time fold (not included in the testcase for
brevity) then the program compiles as expected--this is the workaround that I'm
using in the meantime.
