It's possible that no one can answer you because this was fixed as a
side effect of fixing a different problem.
You might have to resort to a binary search through the subversion
database to find the fix. There's a script in the contrib area of
the gcc sources called reg_search that can help to automate the
process. The endpoints for your search would be the point where
the 4.2 branch was created, and the point where the 4.3 branch was
created, since the fix must have gone into the trunk sometime between
those two points.
