Re-tested:
* gcc-4.7.2 works on amd64, armhf, x32, fails on i386
* gcc-4.8.0 works on all of the above
(all Debian)
So it appears to be fixed

Fails on armhf as well:
lto1: internal compiler error: tree code ‘\�PF9F���G�P.�.lЕ�0�+’ is not
supported in LTO streams
Works on i386.

Ok, works correctly on current trunk as well.
Since the testcase is messy and vulnerable to small alterations, and I guess
the underlying bug fixes already

Correction: after testing with valgrind, the return value is indeed
uninitialized; the pointer in contructor-but-no-fields case happens to be
non-zero
