internal compiler error on -O3 and above

[Matthias Wenzel <mazzoo@xxxxxxxxx>]

Hi gcc monks,

trying to compile mpg123 for a -mcpu=arm926ejs, I get an internal 
compiler error, as long as I use -O3 or above:
---
/home/matze/[...]/bin/arm-linux-gcc -DLINUX     -DOSS -Wall -O3 
-mcpu=arm926ejs          -fomit-frame-pointer -funroll-all-loops 
-finline-functions -ffast-math   -c -o layer3.o layer3.c
layer3.c: In function `init_layer3':
layer3.c:361: error: insn does not satisfy its constraints:

                (plus:SI (reg:SI 10 sl)
                    (const_int 12 [0xc]))) [47 mapend S4 A32])
        (reg:SI 12 ip [1319])) 559 {*arm_movsi_vfp} (insn_list 3628 (nil))

help or hints are appreciated, mpg123 originally comes with the -O6 
switch enabled.
