哪一位高手用过scratchbox进行交叉编译?

[china_clear]

当使用了WMMX指令:_mm_slli_pi32()时
如果编译时使用"-O2"或"-O1"或"-Os"参数,则出现错误:
/scratchbox/compilers/arm-linux-gnueabi/bin/../lib/gcc/arm-none-linux-gnueabi/4.1.1/include/mmintrin.h: In function 'filterHx8BsEq4Chroma':
/scratchbox/compilers/arm-linux-gnueabi/bin/../lib/gcc/arm-none-linux-gnueabi/4.1.1/include/mmintrin.h:451: internal compiler error: in arm_expand_binop_builtin, at config/arm/arm.c:17091
Please submit a full bug report,
with preprocessed source if appropriate.

这是gcc的BUG吗?
有解决方法吗?
先谢谢各位了!
