Well, here is a simple example, tested
on a clean REBOL/View 1.2.8.3.1 3-Aug-2002 (beta)
and a clean REBOL/View 1.2.1.3.1 21-Jun-2001
I could probably do some more experiments
and figure out some more details, but
anyway:
-----------
crash: func ["demonstrates a bug in parse that crashes rebol"
target [any-string!] {try "/../"}
/local start post
][
parse/all target [
start: "/"
any [
"../" post: (remove/part start post)
| to "/" ; to or thru will cause the crash
]
]
]
crash "/../"
-----------
Maybe someone can reduce it further.
