I think this is rather a thingatpt.el issue, which makes no mention of match-data destruction. Regardless, it's decent enough to do that in flymake-diag-region so I pushed save-match-data a bit higher.
By default we assume that any function can destroy match-data (and only a certain set doesn't).
But it's an easy mistake to make, especially given the fairly opaque implementation of (end-of-thing 'symbol).
