The way you track this down is to run with -O3 and progressively add
-fno-* options to disable *successively* (as opposed to sequentially)
more options until you find the one that triggers the failure.

Also, it is important to note that -OX levels add more optimizations
than can be turned on manually with -f options.  ie, -O is more than
just a meta-option for a long list of -f options.
