<pre>Thanks. I've re-committed with a fix for this in 232165.
The main problem was simply that matching operands copied too much of the flag
word from their matched operand. As a result, the bits weren't empty (they
contained the matched operands' constraint id) and it triggered the assertion.
A second problem was that the operand number from a matching operand would be
also be used as the constraint id. Matching operands now obtain the constraint
id from the matched operand.</pre>
