internal compiler error: Segmentation fault

Compiler was crashing when I was trying to run dejagnu testcase with below compilation flags on aarch64-linux-gnu-gcc toolchain.

aarch64-linux-gnu-gcc ../asm-subreg-1.c -fno-diagnostics-show-caret -Og -DSTACK_SIZE=16384 -DNO_LABEL_VALUES -S -o asm-subreg-1.s -fdump-tree-all -fno-section-anchors

asm-subreg-1.c: In function 'evas_common_convert_yuv_420p_601_rgba':
asm-subreg-1.c:14:1: internal compiler error: Segmentation fault
no stack trace because unwind library not available
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
