I can't reproduce the problem from the description with 4.7, but I can
reproduce the problem from comment 4 with 4.7.
Tentative patch for test-case from comment 4:
...
Index: gcc/gimple-low.c
===================================================================
--- gcc/gimple-low.c (revision 181172)
+++ gcc/gimple-low.c (working copy)
@@ -680,6 +680,12 @@ block_may_fallthru (const_tree block)
case CLEANUP_POINT_EXPR:
return block_may_fallthru (TREE_OPERAND (stmt, 0));
+ case DO_STMT:

...
Perhaps we should file a separate bug for the test-case from comment 4.

patch to fix problem in comment 4
(In reply to comment #12)
> Tom, are you handling this?
I submitted a more elaborate version of the patch in comment 11 at
http://gcc.gnu.org/ml/gcc-patches/2011-12/msg00649.html.
Richard Guenther suggested a different way to handle this, and this patch is an
attempt at that.
I tested an earlier version of this patch without any problems, I just need to
retest and submit.

Great, thanks. I would recommend trying to do that before Stage 3 ends.

Well, actually Stage 3 ended while I was in vacations. Sorry about the

I concur with comment 11 that the original problem doesn't occur anymore in
4.4.4 (it still occurred in 4.1.2). Since the variation in comment 4 was also
patched, and being unaware about the protocol, I'll go out on a limp and try to
close this.

Noone cares about 4.4 bugs now, that release has reached end-of-life, but the
problem isn't fixed in 4.5, 4.6 or 4.7 so this isn't FIXED
