FWIW, it builds fine with: gcc-4.7 (Debian 4.7.1-1) 4.7.0

ICEs gcc 4.6.3 and 4.4.7, compiles w/o error with 4.7.1, 4.5.3, 4.3.6, and
4.2.4 (all crosses to ia64-linux hosted on i686-linux).

This was fixed for gcc-4.7.0 by r177658:
http://gcc.gnu.org/ml/gcc-cvs/2011-08/msg00672.html
http://gcc.gnu.org/ml/gcc-patches/2011-08/msg00353.html
The patch applies cleanly to 4.6.3 and cures the ICE on this test case. I
haven't tested the backport beyond that.
For 4.6.3 you can also avoid the ICE by reducing the optimization level to -O2.

Unfortunately r177658 seems to be the cause of wrong-code PR53975.

The trunk (with PR53975 fixed and thus the old patch reverted) ICEs in
av_set_could_be_blocked_by_bookkeeping_p, I will take a look.

--- Comment #7 from Andrey Belevantsev <abel at gcc dot gnu.org> 2012-08-08 11:26:01 UTC ---
Created attachment 27959
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=27959
proposed patch
The problem is that when checking expressions that are blocked for movement
because of recently created bookkeeping code we need to consider also all old
forms of those expressions as they could get transformed on the way up.
PR53975 just uncovers this bug but is actually unrelated.
The attached patch fixes the testcase but is not yet otherwise tested.
