--- Comment #4 from Vadim Zeitlin <vz-gcc at zeitlins dot org> ---
I'd be grateful for any workaround suggestions in the meanwhile. We have one
patch at http://trac.wxwidgets.org/ticket/16359 but it is rather ugly, so it
would be great if someone could propose something better. TIA!

BTW, -O3 is not necessary to see the bug, compiling the test case with just -O
(or -O1, -O2, ...) is enough, it only links without any optimizations at all.
