FAILING ASSERTION: FLEN == LEN
Problem:
Broken invariant triggered when building a unique index on a
binary column and the input data contains duplicate keys. This was broken
in debug builds only.
Fix:
Fixed length of the binary datatype can be greater than length of
the shorter prefix on which index is being created.
