--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Note in GCC 10.3.0 we got:
<source>: In function 'void t(const string&)':
<source>:13:51: warning: 'port' may be used uninitialized in this function
[-Wmaybe-uninitialized]
   13 |         reqb << "Host: " << port.value_or(443) << "\r\n";
