To reproduce the bug I'm using: latexmk -pdf faces.tex

The problem is on the last page (numbered 22), the line before the
last paragraph which starts with "Erst".

The problem goes away if you change (at the end of joh-bernoulli.tex)
the line

  Erst im 20.\ Jahrhundert ...

to

  Erst im 20. Jahrhundert ...

My ~/.latexmkrc looks like this:

********************************

sub asy {return system("asy '$_[0]'");}
add_cus_dep("asy","eps",0,"asy");
add_cus_dep("asy","pdf",0,"asy");
add_cus_dep("asy","tex",0,"asy");

$hash_calc_ignore_pattern{'pdf'} = '^/(CreationDate|ModDate|ID) ';

$pdf_previewer = 'start "c:\\Program Files\\SumatraPDF\\SumatraPDF.exe" %O %S';

$bibtex_use = 2;

$latex = 'latex --enable-write18';
$pdflatex = 'pdflatex --enable-write18';

********************************

I'm on MiKTeX with Windows 10 64-bit.  In case someone wants to dig
into this, I have added my MiKTeX log.
