I'm not sure how the .i ends up with a zero-length array; resolv.h has:
# define MAXNS 3 /* max # name servers we'll track */
[...]
struct __res_state {
[...]
struct sockaddr_in

Also, even if it's invalid input, I guess gcc should never SEGV, but rather
throw an error out?

Reopening since GCC should not ICE, even if the code is invalid.

Ok, it's [0] because ziproxy uses nsaddr as an identifier for a local
variable which conflicts with a compatibility #define in glibc resolv.h.
Renaming to nsaddress for instance fixes the build, so clearly bogus source

Invalid testcase as per comment #6.
(In reply to comment #4)
I see the same problem when I try to compile transmission release 1.73. The
error happens with file libtransmission/fdlimit.c. Works till -O1 but fails

Confirmed with gcc-4.3-20090802, gcc-4.4-20090728, and gcc-4.5-20090730.
Passing -mtune=xscale to gcc prevents the ICE.

Hang on, the test case looks invalid:
ReadCfgFile (char *cfg_file)
{
void *conf_handler;
int i;
struct sockaddr_in nsaddr_list[0];
char *nserver_str;
qp_getconf_array_str (conf_handler, Nameservers, i,
