Dot between chapter number and figure number disapear after update

Question

After a recent update the dot between chapter numbers and figure numbers disappeared. Here is a minimal example.

\documentclass[]{memoir}
\begin{document}
\frontmatter
Some text
\mainmatter
\chapter{Chapter name}
\begin{figure}
  \caption{A figure}\label{A caption}
\end{figure}
Some text~\ref{A caption}
\end{document}

The caption should be "Figure 1.1: A figure", but instead I get "Figure 11: A figure".

Initially, \thefigure has the dot

> \thefigure=\long macro:
->\thechapter .\@arabic \c@figure .
l.2 \show\thefigure

\frontmatter does \counterwithout {figure}{chapter} which resets \thefigure to

> \thefigure=macro:
->\@arabic \c@figure .
l.12 \show\thefigure

Where the dot has disappeard (in the above the final dot is always added by \show).

As part of expansion of \mainmatter we also see

\@secondoftwo #1#2->#2
#1<-\@nocounterr {chapter}
#2<-\@addtoreset {figure}{chapter}\expandafter \gdef \csname thefigure\expandaf
ter \endcsname \expandafter {\csname thechapter\expandafter \endcsname \expanda
fter \@arabic \csname c@figure\endcsname }

Thus again \thefigure is defined without dot.

The latter comes from expansion of:

\@memmain@floats ->\counterwithin {figure}{chapter} \counterwithin {table}{chap
ter}

So it seems \counterwithout/\counterwithin is culprit. Perhaps the recent change in the LaTeX format ?

(I will investigate a bit more and report)

With memoir as in TL2017 I see in the log

\@csin #1#2->\@ifbothcntrs {#1}{#2}{\@addtoreset {#1}{#2}\@namedef {the#1}{\@na
meuse {the#2}.\arabic {#1}}}
#1<-figure
#2<-chapter

With memoir + TL2018 current I see

\counterwithin@x #1#2->\@ifbothcounters {#1}{#2}{\@addtoreset {#1}{#2}\expandaf
ter \gdef \csname the#1\expandafter \endcsname \expandafter {\csname the#2\expa
ndafter \endcsname \expandafter \@arabic \csname c@#1\endcsname }}

This is where the dot has disappeared. Both expand from

\@memmain@floats ->\counterwithin {figure}{chapter} \counterwithin {table}{chap
ter}

but expansion of \counterwithin has changed. The new memoir has

\providecommand{\counterwithin}{\@ifstar{\@csinstar}{\@csin}}
\providecommand{\@csinstar}[2]{%
  \@ifbothcntrs{#1}{#2}{\@addtoreset{#1}{#2}}}
\providecommand{\@csin}[2]{%
  \@ifbothcntrs{#1}{#2}{\@addtoreset{#1}{#2}%
                        \@namedef{the#1}{\@nameuse{the#2}.\arabic{#1}}}}

whereas the former had

\newcommand{\counterwithin}{\@ifstar{\@csinstar}{\@csin}}
\newcommand{\@csinstar}[2]{%
  \@ifbothcntrs{#1}{#2}{\@addtoreset{#1}{#2}}}
\newcommand{\@csin}[2]{%
  \@ifbothcntrs{#1}{#2}{\@addtoreset{#1}{#2}%
                        \@namedef{the#1}{\@nameuse{the#2}.\arabic{#1}}}}

LaTeX of TL2017 did not define \counterwithin:

$ latexdef counterwithin

\counterwithin:
undefined

but LaTeX of TL2018 does define it

$ latexdef counterwithin

\counterwithin:
macro:->\@ifstar \counterwithin@s \counterwithin@x

The cautious \providecommand done by memoir 2018/04/04 v3.7g does not overrule the \counterwithin now from LaTeX. But this one adds no dot...

Thus a report to maintainers of memoir and LaTeX2e is in order...

well this appears to be a LaTeX2e bug because the definition does not include the dot which is in the description:

Good investigation. I did indeed just add \providecommand to memoir to prepare for the new format. Where exactly do you see the text in the image? — daleif, Apr 20 '18 at 11:35

Thanks, hopefully they'll have that fixed soon enough, sad though that this is after the TL freeze — daleif, Apr 20 '18 at 11:39
@daleif the github commit does include a thorough test for many things and among them \counterwithin{footnote}{subsection}, followed by \show\thefootnote with the comment % \thesubsection.\arabic{footnote}. But the committed expectation was without the dot, in contradiction to comment.. thus the commit went through the validation. I feel sympathy for having myself pushed an update to a package a bit in haste when I belatedly realized TeXLive schedule had been advanced by one full month. Bugs creep-in even in validation suites... — , Apr 20 '18 at 12:24

Until the error is fixed in the new LaTeX format, you can explicitly use the version that memoir still provides by using

\makeatletter
\renewcommand{\counterwithin}{\@ifstar{\@csinstar}{\@csin}}
\makeatother

in your preamble.

Thanks to jfbu for the analysis.
