arm-eabi toolchain memcpy using hard float causing unaligned access

Hi Linaro Team, I'm currently using toolchain gcc-linaro-7.1.1-2017.08-x86_64_arm-eabi.tar.xz https://releases.linaro.org/components/toolchain/binaries/latest/arm-eabi/gcc-linaro-7.1.1-2017.08-x86_64_arm-eabi.tar.xz to develop my bera-metal programs. My compile option is "-marm -march=armv7-a -mtune=cortex-a9 -mlittle-endian -mfloat-abi=hard -mfpu=neon"

I found an issue, when I use memcpy, and if the DEST or SOURCE address is not 4 bytes aligned, the system hangs. It seems that this toolchain doesn't support using hard float and NEON ?

My question is does this toolchain support hard float and NEON in the newlib C library? If I want to use hard float and NEON, how can I do that?

Your reply is more appreciated!!
