Hmm. I get the ICE with 4.2.0 20060407. Will try a newer one...

I can confirm that this test case works with 20060408. However, a slightly
longer test case (directly from delta, without Falk's manual reduction) still
produces a segfault, but only when you pass -finline-functions:
(sid)127:tbm@deprecation: ~] cat m.c
typedef struct { unsigned int size; } gnutls_datum;
typedef struct gnutls_cert { gnutls_datum raw; } gnutls_cert;
typedef struct gnutls_privkey_int { } gnutls_privkey;
typedef struct gnutls_session_int *gnutls_session;
extern int _gnutls_log_level;
_gnutls_gen_x509_crt (gnutls_session session, unsigned char ** data)
{
int ret, i;
unsigned char *pdata;
gnutls_cert *apr_cert_list;
gnutls_privkey *apr_pkey;
int apr_cert_list_length;
if ((ret =
_gnutls_get_selected_cert (session, &apr_cert_list,
&apr_cert_list_length, &apr_pkey)) < 0)
{
if (_gnutls_log_level >= 2 || _gnutls_log_level > 9)
_gnutls_log (2, "ASSERT: %s:%d\n", "auth_cert.c", 665);
}
for (i = 0; i < apr_cert_list_length; i++)
{
_gnutls_write_datum24 (pdata, apr_cert_list[i].raw);
pdata += (3 + apr_cert_list[i].raw.size);
}
}
_gnutls_get_selected_cert (gnutls_session session,
gnutls_privkey ** apr_pkey)
{
}

------- Comment #5 from reichelt at gcc dot gnu dot org 2006-04-13 12:00 -------
Confirmed.
The original testcase compiles fine for me with today's compiler.
If I remove the (unused) typedef in the third line, I get the ICE.
Here's a reduced testcase:
=================================
struct A { int i; };
struct B { struct A a; };
int N;
void foo(struct B *p, char *q)
{
if (N)
bar(p->a, q);
q += p->a.i;
}
=================================

Forgot to mention that you have to compile the testcase from comment #5
with "-O2".
