Fix panic when using pattern synonyms with DisambiguateRecordFields · 4f69203d

Adam Gundry authored 9 years ago and

Ben Gamari committed 9 years ago

This fixes a `find_tycon` panic when constructing a record pattern
synonym when `DisambiguateRecordFields` (turned on by `RecordWildCards`)
is enabled.  The handling of record wild cards in such constructions
isn't completely satisfactory, but doing better will require the
`Parent` type to be more informative, as I'll explain on #11228.
