[bug #47569] GRUB 2.02~beta2 "fatal error: token too large, exceeds YYLMAX"

[Alvaro Gonzalez]

Follow-up Comment #2, bug #47569 (project grub):

Hello,

But couldn't grub recover from the error a bit better? It shows in a infinite
loop (looks like infinite) the error:

"fatal error: token too large, exceeds YYLMAX"

...and it is impossible (as far as I know) to fix without booting from an
different drive or similar to edit the config.

Could it just fail and leave you in a grub prompt? Bonus points if it lets you
see the configuration you have and edit it. And more bonus points if the same
parsing that it uses during boot to show the YYLMAX error is used in
grub-mkconfig or a new grub-checkconfig is created.

Regards
