Hans Bezemer reported an input stack overflow while processing the page footer
when using the mmse.tmac localization file for Swedish.

(The formatter exits in a controlled way; this stack is not the execution
stack employed by the OS process.  It would be an infinite loop if the
`slimit` register of GNU troff were not set to a small finite value.)

The problem is a missing scaling indicator in the macro file.

Problem affects groff 1.22.4 and appears to date back 22 years, to the
introduction of the file.  That's a DNAMN long time!
