Please submit a full bug report,
with preprocessed source if appropriate.
See <https://bugs.launchpad.net/gcc-linaro> for instructions.

Please find the attached testcase to the bug cases.

Observation:
  compiler is crashing when we use -Og flag. I digged it further and found that it is crashing in reload pass.

 Can any one please let me know how to fix this.

 Toolchain details:
Name: aarch64-linux-gnu-gcc
Version: Linaro GCC 2013.10

  Please let me know if any additional details are required

Thanks,
