When building perl in my customary manner on Linux, I am getting the
following new build-time warning​:

#####
./miniperl -Ilib autodoc.pl
embed.fnc entry 'sv_utf8_upgrade_flags_grow' missing 'd' flag at
autodoc.pl line 135, <F> line 3479.
#####

The relevant code in autodoc.pl​:

#####
131 if ($embed_docref and %$embed_docref) {
132 warn "embed.fnc entry overrides redundant
information in"
133 . " '$proto_in_file' in $file" if $flags || $ret
|| @​args;
134 $flags = $embed_docref->{'flags'};
135 warn "embed.fnc entry '$name' missing 'd' flag"
136 unless
$flags =~ /d/;
137 $ret = $embed_docref->{'retval'};
138 @​args = @​{$embed_docref->{args}};
139 } elsif ($flags !~ /m/) { # Not in embed.fnc, is
missing if not a
#####

On the basis of when embed.fnc has most recently, I suspect a commit
more recent than 03b7d27 (applied to
blead July 22).

  PATCH​: [perl #134357] embed.fnc missing flag for docs
 
  A check was recently added if a function had documentation that
  embed.fnc accurately reflected that. Commit
  c1a02cc missed this function
