bug#55269: 29.0.50; Infinite recursion causes segmentation fault

bug#55269: 29.0.50; Infinite recursion causes segmentation fault

[Philip Kaludercic]

Note, I cannot reproduce this with "emacs -Q", but I don't think that
any user customisation should allow for this to happen.  All I need to
do is evaluate

   (defun fix () (fix)) ; -> works
   (fix)                ; -> crashes emacs

I have tried to investigate the issue in GDB, but all I get there is an
apparently never ending stacktrace:

Did you customize max-lisp-eval-depth?

C-h o says it wasn't customised, and the value is 800.  I have also
re-built Emacs without any fancy compiler flags (besides -ggdb3 and -O0)
or other optimisations.

Hm...  so the backtrace here seems to say that skip_debugger (which is
supposed to be a predicate) is itself bugging out (i.e., the
Ferror_message_string is erroring)?

Hm...  Oh, it's coming from here?

void
print_error_message (Lisp_Object data, Lisp_Object stream, const char *context,
		     Lisp_Object caller)
[...]
      if (!NILP (Ffboundp (Qsubstitute_command_keys)))
	errmsg = call1 (Qsubstitute_command_keys, errmsg);

I think the fix here would be to ensure that that call never signals an
error (i.e., slap a condition-case around that call1).  I.e., could you
try this patch and see whether it fixes the problem?

I can confirm this solves the problem.  Thanks!

Thanks; pushed to Emacs 29 now.

I think this is a recent regression, so I cherry-picked this fix to
the emacs-28 branch.
