This works correctly for i386-darwin.
In fact I tried -std=c99 -O1 -mfpmath=387 -march=pentium4 -mno-sse too.

In fact, with -mno-sse the problem disappears for me too.
I *do* get the problem with
gcc -std=c99 -O1 -march=i386 -msse2 -mfpmath=387

Still works correctly on i386-darwin but that might be because PIC is turned on
by default.

Fails

cprop_hardreg pass is propagating DImode ax register, wrongly bypassing DI-SI
conversion.
Before cprop_hardreg, we have:
(call_insn/u:HI 27 88 28 4 pr37544.c:9 (set (reg:DI 0 ax)
(call (mem:QI (symbol_ref:SI ("__fixunsdfdi") [flags 0x41]) [0 S1 A8])
(const_int 16 [0x10]))) 687 {*call_value_0} (expr_list:REG_UNUSED
(reg:SI 1 dx)
(expr_list:REG_EH_REGION (const_int -1 [0xffffffff])
(nil)))
(expr_list:REG_DEP_TRUE (use (mem:DF (plus:SI (reg/f:SI 7 sp)
(scratch:SI)) [0 S8 A8]))
(nil)))
(insn 95 28 104 4 pr37544.c:9 (set (reg:SI 21 xmm0)
(reg:SI 0 ax [78])) 41 {*movsi_1} (expr_list:REG_DEAD (reg:SI 0 ax
[78])
(nil)))
(insn 104 95 105 4 pr37544.c:9 (set (mem/c:DI (plus:SI (reg/f:SI 6 bp)
(const_int -8032 [0xffffe0a0])) [0 S8 A64])
(reg:DI 21 xmm0)) 63 {*movdi_2} (expr_list:REG_DEAD (reg:DI 21 xmm0)
(nil)))
(insn 105 104 89 4 pr37544.c:9 (set (reg/v:DF 8 st [orig:65 b ] [65])
(float:DF (mem/c:DI (plus:SI (reg/f:SI 6 bp)
(const_int -8032 [0xffffe0a0])) [0 S8 A64]))) 179
{*floatdidf2_i387} (nil))
and after cprop_hardreg:
(call_insn/u:HI 27 88 28 4 pr37544.c:9 (set (reg:DI 0 ax)
(call (mem:QI (symbol_ref:SI ("__fixunsdfdi") [flags 0x41]) [0 S1 A8])
(const_int 16 [0x10]))) 687 {*call_value_0} (expr_list:REG_UNUSED
(reg:SI 1 dx)
(expr_list:REG_EH_REGION (const_int -1 [0xffffffff])
(nil)))
(expr_list:REG_DEP_TRUE (use (mem:DF (plus:SI (reg/f:SI 7 sp)
(scratch:SI)) [0 S8 A8]))
(nil)))
(insn 95 28 104 4 pr37544.c:9 (set (reg:SI 21 xmm0)
(reg:SI 0 ax [78])) 41 {*movsi_1} (expr_list:REG_DEAD (reg:SI 0 ax
[78])
(nil)))
(insn 104 95 105 4 pr37544.c:9 (set (mem/c:DI (plus:SI (reg/f:SI 6 bp)
(const_int -8032 [0xffffe0a0])) [0 S8 A64])
(reg:DI 0 ax [21])) 63 {*movdi_2} (expr_list:REG_DEAD (reg:DI 21 xmm0)
(nil)))
(insn 105 104 89 4 pr37544.c:9 (set (reg/v:DF 8 st [orig:65 b ] [65])
(float:DF (mem/c:DI (plus:SI (reg/f:SI 6 bp)
(const_int -8032 [0xffffe0a0])) [0 S8 A64]))) 179
{*floatdidf2_i387} (nil))
Please note, how DImode ax reg propagates into (insn 104), bypassing SImode
conversion in (insn 95).

The problem is in regrename.c, function maybe_mode_change. We enter the
function with:
orig_mode = DImode
copy_mode = SImode
new_mode = DImode
At the beginning of maybe_mode_change() we have:
if (orig_mode == new_mode)
return gen_rtx_raw_REG (new_mode, regno);
we simply discard the change to a narrower mode.
