pdfcrop bounding box problem

[Alan Munn]

Hi, the following document, processed with any engine, crops improperly.
Perhaps this is a ghostscript problem, but I'll post it here in case
anyone can figure it out.

\documentclass{article}
\pagestyle{empty}
\begin{document}
\shipout\vbox
{\parbox{1.75in}{%
\centering
\raggedleft
\vspace{.25in}\par\fontsize{11}{13}\selectfont
Some Text\par\vspace{12pt}
\fontsize{10}{12}\selectfont
Some more text\par%
\vspace{12pt}\fontsize{8}{10}\selectfont
Even more text\par
\vspace{10pt}
Something else\par}
}
\end{document}

The output of pdfcrop (TL 2019, running on a Mac).  David Carlisle also
replicated this behaviour using cygwin.
