Created attachment 42251

(simplified) Preprocessed source code, generated by adding -save-temps
I managed to narrow down the problem (see attachment). I was wrong about the
function template recurrency. Problem is associated with the parameter pack of
size 0 or 1 in SFINAE test.
Confirmed with gcc: 8.0.0, 7.2.0, 7.1.0, 6.3.0, 6.2.0, 6.1.0, 5.4.0, 5.3.0,
5.2.0, 5.1.0, 4.9.3, 4.9.2, 4.9.1, 4.9.0, 4.8.5, 4.8.4, 4.8.3, 4.8.2, 4.8.1.
Below version 4.8.1 (4.7.4 and below) everything is okay.
