Crash when there is a Cut operator which doesn't belong to a PrioritizedChoice operator

[kfsone]

The following grammar causes the playground to lock into an infinite loop:

p <- (a E)*
~E <- '\n' / !.
a <- 'x' '=' ↑ t   # << removing the cut solves the problem
t <- 'a' | 'b'

@kfsone, thanks for the report, but I can't reproduce it on the playground.

Also I am not able to reproduce it with peglint either.

Ah, sorry, try the input:

x=c

[yhirose]

Thanks. I am now reproduce it.

This is actually not a infinite loop problem. This is caused by a Cut operator which doesn't belong to a PrioritizedChoice operator. I changed the title.
