Bug ID: 69365
Summary: LWG DR2367 (constrained pair default constructor)
Product: gcc
Version: 5.3.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: Casey at Carter dot net
Target Milestone: ---
There's a bug report for range-v3
(https://github.com/ericniebler/range-v3/issues/275) that results from
libstdc++ in the GCC-5 branch not implementing the resolution of LWG2367
(constraining the default constructor of std::pair & std::tuple). I'm aware
that 2367 is fixed on trunk - is there any possibility of the fix being
backported to gcc-5-branch?
