Bug ID: 82218
Summary: [C++1x] constexpr on static member function causes
segfault
Product: gcc
Version: 6.3.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: emil.fresk at gmail dot com
Target Milestone: ---
The constexpr on line 55 in Compiler Explorer https://godbolt.org/g/sJA8nK
causes the segfault.
By removing this, it compiles fine.
The error is tested in 6.3.0 and 6.3.1, where it exists.
Found on arm-none-eabi-gcc 6.3.1 on Ubuntu 16.04, reproduced on the normal GCC
6.3.x.
Not triggered any more in GCC 7.1 and 7.2.
