You are right. I was suspicious about the pr45230 having no .c extension in the
file name (weird). So I renamed the file and test it again.
bash-4.1$ ./xmingw-trunk-w64-sjlj/bin/x86_64-w64-mingw32-gcc -w -Os -lm -m32
-fgraphite-identity -c pr45230.c

Did few more tests and found the g++ failed at -O1 not -Os for
qdrawhelper_mmx.ii
The gcc failed at -Os and not -O3 for pr45230.c

Ok this ticket is getting very confusing now and no development recently.
------- Comment #12 From Zdenek Sojka 2010-09-15 18:39 [reply] -------
You are compiling it without graphite and yet you are using graphite branch to
test. Then you are getting another type of ICE.
------- Comment #10 From t66667@gmail.com 2010-09-15 00:17 [reply] -------
Based on my observations the bug in PR45406 is triggered differently but with
the same ICE and different language C C++.
------- Comment #3 From Sebastian Pop 2010-08-20 23:50 [reply] -------
Can you tell us a little more about what is going on in this PR45230.
Are you still working on the problem ?
If not I will detach PR45406 from this ticket.

(In reply to comment #16)
> Fixed.
sorry you only introduced the problem into another error.
this maybe multiple problems.
what did you fix, which revision?
should i un-mark duplicate to pr45406 ?
since pr45406 and the testcase which zdenek attached in comment #2 is still
valid.
so i will reopen the problem.
do you want to fix pr45406 ?
it is not a good sign you do not say nothing.

Mine. On trunk r167554 I see this failing:
./xgcc -B. -fgraphite-identity -Os -m32
gcc/testsuite/gcc.c-torture/execute/strncmp-1.c
in sese.c:
tree rhs = gimple_assign_rhs1 (copy);
and here copy is a call statement.
