Description
The attached program collator_index_test.c sets up a collator on an index. During the second insertion, the collator compare is called with the expected key from the insertion, but with an unexpected key from the tree, a single null byte. The collator doesn't know what to make of this - it doesn't look like a (value,key) pair that can be decoded.
The caller of the callback is row_srch.c:294, which seems to be handling appends in a fast-path. If the fast-path code is commented out, it gives normal callbacks.
This test case is derived from attachment jcurs_u_extr_index_coll.c in WT-2308

{u'username': u'keithbostic', u'name': u'Keith Bostic', u'email': u'keith@wiredtiger.com'}Message: WT-2368: row-store can pass garbage keys to collator functions
When searching internal pages, row-store search does a fast check to see
if we're appending to a tree. We weren't ignoring the internal page's 0th
key in that code, that is, we were handing it to the collator. Since the
0th key may not even exist, it has to be ignored.
