Well, if it's CVS HEAD, it's not a "release".
Anyway, please post self contained (reduced if possible) sources showing
the problem, as well as standalone command line (simplified if possible).
Thanks.

Thanks for the sources. If you get a chance to reduce the problem, that
will certainly give this report higher priority.
I am also surprised by the location: tree-ssa-structalias.c, I thought
strict aliasing was disabled for Ada. Are you using FSF GCC sources or sources
modified ?
(btw, is there a way to remove the 'waiting' state without confirming the PR ?)

Hi Arnaud,
The HEAD is indeed a typo - should have been release_2_1a. For head we have a
different problem (bug:26162).
As for the compiler, it is the unmodified release version:
GNAT 4.1.0
gcc (GCC) 4.1.0
With Regards
Martin

Structure aliasing is indeed disabled for Ada but tree-ssa-structalias.c
contains the generic points-to analyser, aka "constraint solver".

A note is that it works on x86_64 (and I cannot test i686 because Ada does not
have mulitilib support:( ).
if Ada did have multilib support I could reduce this easier.

Hello Andrew,
you are right - the hole of AWS compiles nicely with x86_64.

------- Comment #10 from matz at suse dot de 2006-05-03 15:40 -------
We also got a bugreport about an ICE in get_constraint_for_component_ref,
but have a C testcase. In the hope that it's the same reason I paste it
here:
---------------------------------
/* compile with gcc -c -O2 -o foo.o foo.c */
typedef struct {
struct { } z;
} thang_t;
struct widget {
struct widget *p, *q;
};
typedef struct thing {
struct widget x;
} thing_t;
struct {
int a;
int b;
int c;
int d;
int e;
thang_t f;
thing_t g;
} my_struct;
static void foo(thang_t *r)
{ splat(r);}
void function(int blaz)
{ foo(&my_struct.f);}
--------------------------------------
This fails with 4.1.x on x86_64 with -O1 and beyond.
