Bug ID: 70977
Summary: Error during compilation of facebook/wangle (flag
c++0x works, flag c++14 fails).
Product: gcc
Version: 6.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: aleksandergajewski at gmail dot com
Target Milestone: ---
GCC version as follows: (nothing but svn checkout release_6_1.. && ./configure
--prefix=/usr && make && make install):
adiog@box:~/dev/wangle/build-6.1$ c++ --version
c++ (GCC) 6.1.0

The problem should be easy to reproduce (compilation fails on first file in a
project). I have compiled https://github.com/facebook/wangle, but with changed
flag from -std=c++0x to -std=c++14. In first case compilation terminates after
few seconds, in second one there is a gcc internal error (after few minutes
with whole ram 4gb and whole swap consumed). htop does not show any cpu usage.
