Bug ID: 78774
Summary: Internal compiler error segmentation fault: constexpr
string literals and templates
Product: gcc
Version: 6.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org

Breaking code
The sample code works well in GCC 4 and 5. It breaks at least in 6.2.0 and
6.2.1 and both in openSUSE and Ubuntu. I would appreciate some workaround tips
until the issue is fixed.
