bug#34043: 26.1; ada-mode 6.0.0: Ada > Misc > Reset parser emits an error message

[Ludovic Brenta]

Package: emacs
Version: 26.1
X-Debbugs-CC: ada-mode-users@nongnu.org
Severity: minor

After opening any Ada file, if I go to the menu Ada > Misc > Reset 
Parser, I get:

wisi--delete-face-cache: Args out of range: 0, 37

with the "37" being the value of (point-max) for this buffer.

I don't know whether this is a genuine problem or a false error message.
