This is an ugly hack to work around a problem. Emacs doesn't shy away
from ugly hacks to work around problem, but we should make every effort
to document the problem so that if someone has the time&energy to try
and find a better fix they know where to look.
IOW, could you make a bug-report of the problem (ideally with
a reliably reproducible recipe and/or a backtrace) and link to it in the
above comment?

The problem happens sporadically only. And IIRC, it happened only with
Emacs <=26. max-specpdl-size was increased in Emacs 27.

A bug report would be useless. I've added this information to the comment.

Just a little bit of more info. This happens to me just on
emacs23. But. Perhaps are other opinions about this.
Best Regards
