--- Comment #16 from Michael Catanzaro <mcatanzaro at redhat.com> ---
And specifically only at -O2 optimization level, so that narrows things down significantly. It could be a GCC bug, or it could be undefined behavior in JSC.

Since almost all distros build with GCC and -O2, yet only you are complaining, it might also occur only in combination with one of the other compiler flags you use.
