bug#60352: 30.0.50; Keep getting "Error in syntax_table logic for to-the-end intervals"

[Ihor Radchenko <yantar92@posteo.net>]

Hi,

I keep getting the following backtrace:

Debugger entered--Lisp error: (error "Error in syntax_table logic for to-the-end intervals")
  (re-search-forward "\\(?:\\(?:\\<DEADLINE: *\\(\\(?:<\\(?:[[:digit:]]\\{4\\}-[..." nil move)

It only happens in Emacs 30 (master) and is not regular.

The error sounds like some kind of internal error.
Does it signify some Emacs issue? Or may it be third-party code issue?

Best,
Ihor
