This is likely to be the source of the problem. Make sure you build
not only libgcc, but also libio, libstdc++ and probably also glibc
with this flag.
I did a complete bootstrap build, which takes care of libio and libstc++; I
haven't rebuilt libc in quite some time and frankly, I don't remember which
flags I used there, although I can rebuild it with -malign-double and see what
happens. Before doing this, I'll try lowering the optimization and keeping
-malign-double in gcc.
BTW: I routinely add -malign-double for all apps on an i[56]86. I've not
encountered this problem elsewhere.
