Haskell: spurious character in .cf file leads to ill-formed semantic parse actions #214
Description
A. S ::= "A"; x -- Here is a superfluous character
B. S ::= "B";
BNFC swallows this, but then the generated parser does not compile.
In the .y file, this grammar turns into:
S :: { S }
S : 'A' { Min.Abs.A } | 'B' { Min.Abs.x_ }
