Further tests have indicated (though not proven, at least for point a)
a) ffreep is only emitted if -march=native is used (which I added in an
attempt to fix point b) and
b) xulrunner-220.127.116.11 mistakenly enables SSE1 (not ffreep, but also
causing SIGILL) on all x86 hosts .
So while still a serious compiler issue (and reported before for a
different processor ), it only seems to happen if additional compiler
options are passed.
