"Matching region end for" message

[Angelo Graziosi]

Casually, in Messages buffer I found this:


Starting new Ispell process ~/.emacs.d/aspell.cmd with default dictionary...done
Spell-checking foo.tex using aspell.cmd with default dictionary...
Matching region end for ‘/foo.tex’ point 135 not found
[...]

What does it mean the last row?

For the sake of completeness, aspell.cmd is this:

$ cat .emacs-w64.d/aspell.cmd
@echo off
wsl aspell %1 %2 %3 %4 %5 %6 %7

TIA
