Works fine with
gcc (GCC) 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)
And did work with trunk until recently (at least end of december, IIRC)

First file:
extern struct globals *const ptr_to_globals;
struct globals { };
int syslogd_main(int argc, char **argv)
{
(*(struct globals**)&ptr_to_globals) = 0;
}
----- CUT -----
Second file:
extern struct globals *const ptr_to_globals;
---- CUT -----
-O2 is enough to reproduce this.
