I tracked a bug in the ObjC compiler which was causing -fstrict-aliasing
to generate incorrect code for your testcase (and other testcases as
well!), fixed it, and committed the fix to the 3.1 branch of GCC CVS (and
am now committing to the main branch).

I think this should fix at least this problem - 3.1.1, which should be out
on 15th July, should then contain the fix.

Problem is - I tried the fixed compiler, and I still don't get a working
gnustep system ... gdnc dies silently when apps connect to it.  :-(

It takes a lot of time to rebuild everything, and I am running out of
time, so it may be I didn't rebuild everything cleanly enough ... or maybe
there is still something wrong - if you/someone can get accurate
reports/description of what's going wrong (if anything still is after the
fix), I can look further into fixing further problems.
