The test-case is creduced.
Only the GCC5 fails, gcc-4.9, 6 and 7 do not.
clang-3.9, 4, 5, trunk is also fine with that code.
$ g++-7 -std=c++14 -c main.cpp
$ g++-6 -std=c++14 -c main.cpp
$ g++-5 -std=c++14 -c main.cpp
main.cpp: In instantiation of ‘d::n() const::<lambda(auto:1, d::h, d::h,
int, d::n() const::p, d::n() const::p)> [with auto:1 = d::n()
const::<lambda()>]’:
main.cpp:26:28: required from here
main.cpp:23:11: error: ‘e’ is not captured
if (e < e)
^
main.cpp:23:11: note: ‘const int& e’ declared here
I'm unable to report this upstream, since registration is closed, and
password recovery does not seem to function.
Roman.
