I have applied for an account for submitting bugs of clang, but no response
from the administrators. So I have to send mail to this forum.

Yes. I conpiled it with std=c++1z; but the bug still exists.

Hi,
Deducing template parameters for constructors is a C++17 feature. You
need to pass the -std=c++1z flag to the compiler.
