C++ source code

I just tried to compile the package armacycles-ad-0.2.8.3.1 with the
latest trunk snapshot 20111001 on an AMD x86_64 box.

The compiler said

/home/dcb/rpmbuild/BUILD/armagetronad-0.2.8.3.1/bindist/../src/tools/tRecorderInternal.cpp:311:46:
internal compiler error: in ipa_get_jf_pass_through_result, at ipa-cp.c:641
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

Preprocessed source code attached. Flag -O3 required.

Confirmed, the problem is that is_gimple_ip_invariant returns false
for

  &MEM[(struct tRecorderImp *)&recorder + 8B]

where &reorder is an IP gimple invariant, which I believe is wrong.
I'll try to address this.

Simple testcase

Simplified testcase, -O3 -fno-early-inlining required, fails for me at i686 but
will most probably just fail anywhere now.
