arm/thumb disassembler: display problem?

Hi!

snipped from my __uClibc_main, compiled with gcc-3.0.3 and objdumped
with binutils-2.11.2:

  54:   1c0f            mov     r7, r1         (add r7, r1, #0)
  56:   480b            ldr     r0, [pc, #44]  (84 <__uClibc_main+0x34>)
  58:   490b            ldr     r1, [pc, #44]  (88 <__uClibc_main+0x38>)
  5a:   1c14            mov     r4, r2         (add r4, r2, #0)
...
  7e:   f805f000        bl      8c <exit>
  82:   0000            lsl     r0, r0, #0
  84:   003c            lsl     r4, r7, #0
  86:   0000            lsl     r0, r0, #0
  88:   0010            lsl     r0, r2, #0
  8a:   0000            lsl     r0, r0, #0

Look at 0x56 and 0x58: they can't be both 'ldr rx, [pc, #44]', can they?
At least one of the loads would be misaligned. As the hardware executes
it without complaint and the address in parenthesis shows what really
happens I assume it's a simple bug in the display logic.

Is it obvious to those knowing the code or shall I try to produce a
boilt down testcase?
