Hi!
Using the grammar below we experience unexpected behavior. The parser
accepts the following input line:
<<<<<<< .mine
without throwing an error - which it should - according to the grammar.
The grammar has been reduced to
a toy example reproducing the error. Any thoughts on that?
Regards, Chris
