But note that PR 7618 is target specific--the PR notes that the
problem is fixed for i686 in 3.3.3 and probably also in 3.2.3.  My
inspection of the source code suggests that it ought to work for i386
in 3.2.3, although I haven't tested it.

In 3.4 the bug is fixed for all popular targets, but it still remains
for a number of minor targets.
