I get an "undefined reference" error when linking two files but that variable
is static.  This only happens with gcc 4.2, and only when I enable both -g and
-O1 (or higher).

(sid)473:tbm@reyes: ~] cat test.c
static const char utf8_skip_data[1] = {1};
static const char * const gconf_g_utf8_skip = utf8_skip_data;
(sid)474:tbm@reyes: ~] cat main.c
int main() {
}
(sid)475:tbm@reyes: ~] gcc -c -o main.o main.c
(sid)476:tbm@reyes: ~] gcc -c -g -O2 -o test.o test.c
(sid)477:tbm@reyes: ~] gcc main.o test.o
test.o:(.debug_info+0x93): undefined reference to `utf8_skip_data'
collect2: ld returned 1 exit status
zsh: exit 1     gcc main.o test.o
(sid)478:tbm@reyes: ~] gcc-4.1 -c -g -O2 -o test.o test.c
(sid)479:tbm@reyes: ~] gcc main.o test.o
(sid)480:tbm@reyes: ~] gcc -c -g -O0 -o test.o test.c
(sid)481:tbm@reyes: ~] gcc main.o test.o
(sid)482:tbm@reyes: ~]

This is with 4.2.0 20060419.  20060517 shows the same.
