Thirunarayanan B 9ea02a1c09 Bug #18010711 UNIQUE PREFIX INDEX ON BINARY COLUMN:

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.
