C++ Constructor Initialization Failure for Cortex-A8

[Thomas Kim]

Dear Sir,

I am testing cxx example including C++ global constructor in example-v2 on
Cortex-A8 based board.

As I remembered in csae of using cxx example on Sparc SIS, I resolved this
after removing below options according to your comment.
  CFLAGS_OPTIMIZE_V += -ffunction-sections -fdata-sections
  LDFLAGS = -Wl,--gc-sections

But, when I test same cxx example on ARM Cortex-A8 board, I have similar
problem as like below;
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
terminate called after throwing an instance of
'__gnu_cxx::__concurrence_lock_error'
  what():  __gnu_cxx::__concurrence_lock_error
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

At this time, I used below config options for Cortex-A8.
CPU_CFLAGS = -march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp
CFLAGS_OPTIMIZE_V ?= -O2 -g

also, I am using RSB GCC 4.8.2 as like below;

Please let me  know how to resolve this problem ?
