Description:
In an UPDATE IGNORE statement
unique contraint violations are not
ignored if on non-primary key.

How to repeat:
Do an UPDATE IGNORE
that violates uniqueness constraint of
non-primary key.

Suggested fix:
Should be fixed along the line of fix for
Bug #17431  	INSERT IGNORE INTO returns failed: 1296: err 4350 'Transaction already aborted'
, but with extra checks if the update modified a row with the same value
for the possibly conflicting key value.
