Description serge_sans_paille 2019-02-19 08:31:16 UTC 
Following test case compiles fine with gcc-8.2 but fails to build with gcc-9

    https://godbolt.org/z/c3iMsT

One now needs to manually forward the construct method, and I'm unsure why this is needed.

The problem arises with gcc-9.0.1 used to recompile fedora-30
Comment 1 serge_sans_paille 2019-03-06 13:01:51 UTC 
Problem fixed in trunk version (see godblot) and in g++ (GCC) 9.0.1 20190227 (Red Hat 9.0.1-0.8), closing the issue.
