You are accessing a pointer of type char *s1 via an lvalue of type void *
(*data). Or speaking in C++, you are accessing an object of dynamic type
void * (stored to via *data) by an lvalue of type char * (s1).
Thus your testcase invokes undefined behavior.
That it is miscompiled at -O1 is a bug.
With GCC 4.6 we now assign the same alias-set to all pointers, hiding
this issue.
data_4 is a non-pointer variable,ignoring constraint:*data_4 = s2.1_5
data_4, points-to vars: { }
oops. I will have a look at the points-to bug.

--- Comment #17 from rguenth at gcc dot gnu dot org 2010-09-15 13:03 --- points-to analysis does not honor GCCs type-punning through union extension (it works on x86_64 because ptr and asBits match in size and thus SRA cleans the code up before pointer-analysis). So PTA sees ss1.0_1 = ss1; l.ptr = ss1.0_1; D.3244_2 = l.asBits; m.asBits = D.3244_2; D.3245_3 = m.ptr; data_4 = (void * *) D.3245_3; and it considers both D.3244_2 = l.asBits and m.asBits = D.3244_2 as irrelevant (as they do not involve pointers). Thus, m.ptr is never assigned to and the points-to set of data_4 ends up as empty which makes us remove the store *data_4 = s2.1_5. Thus, as a workaround you should make sure the asBits field matches pointer-size (so for example use uintptr_t isntead of uint64_t). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45623

--- Comment #8 from rguenth at gcc dot gnu dot org 2010-09-10 13:26 ---
(In reply to comment #6)
(In reply to comment #5)
I see before SLP:
bb 2:
MEM[(struct A *)this_1(D)].a = 0;
MEM[(struct A *)this_1(D)].b = 0;
MEM[(struct A *)this_1(D)].c = 0;
[LP 2] MEM[(struct A *)this_1(D) + 12B].a = 0;
and after:
bb 2:
vect_cst_.1_16 = { 0, 0, 0, 0 };
vect_p.5_17 = MEM[(struct A *)this_1(D)].a;
M*vect_p.5_17{misalignment: 0} = vect_cst_.1_16;
so EH info has not been properly transfered.
How should it be done? Is it ok to assume that if one of the old stmts can
throw, then we can set TREE_THIS_NOTRAP for the new access to 0? (and then we
can call maybe_duplicate_eh_stmt (new_stmt, old_stmt)).
Or maybe it's better to avoid vectorization?...
I think it's best to avoid vectorization if one of the old stmts can
throw.
Richard.
