I get the same error with gcc-snapshot in Debian (gcc trunk r249349).
Next stop bug tracker.

​It compiles if I set CXXFLAGS to -std=c++1z or -std=c++14
and fails again with -std=c++11

​I managed to confuse myself with all those flags -- it compiles with ​ -std=c++1z
fails with either -std=c++11 or std=c++14:

<<<<
HG ID for this build is "6fe13cd3543c"

​....
​__octave_config_info__ ("CXXFLAGS")
ans = -O2 -std=c++1z
