And it seems to have some issues:

Comments #4 and #6.
The only real issue here is a wrong expectation: That a certain
combination of flags magically does the best thing for every target.
The -Ox options are "tuned" from time to time to get the best mix of
results of a certain set of targets. That does not mean it does the
best thing for all other targets. Then, folks who like to complain
come along and report silly bugs like this, when perhaps they should
also notice that the efficiency of GCC for -Os has increased
tremendeously in the past few years...
Just my US$0.02 about this particular bug.
