OK, tried again...

Tested gcc -O1 again just to make sure, and the workaround fails.

So, decided to try the individual option that -O1 is supposed to enable
according to the manual:
http://gcc.gnu.org/onlinedocs/gcc-4.3.3/gcc/Optimize-Options.html#Optimize-Options

Annoyingly, this bug doesn't pop up when enabling all the options listed under
-O1.  So either -O1 is doing something that isn't documented, or it is doing
something it shouldn't.

Had problems compiling GCC 4.4.0, but I'll give it another go later and try and
figure out what is going on.
I'm still leaning toward a GCC bug, but I still need to prove it.
