Actually I just reproduced it on the mainline (20040310):
./cc1 pr14322.c -m64 -fPIC
 f

pr14322.c: In function `f':
pr14322.c:5: error: unrecognizable insn:
(insn 11 10 12 0 (set (reg:DI 112)
        (lo_sum:DI (reg:DI 112)
            (unspec:DI [
                    (symbol_ref:SI ("foo") <var_decl 0x40eea5e4 foo>)
                ] 0))) -1 (nil)
    (nil))
pr14322.c:5: internal compiler error: in extract_insn, at recog.c:2074
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

Now if I do:
./cc1 pr14322.c -m64 -fPIC -mptr64
It works, so this is a target bug.
