Branch 0.y.z segfault on Android NDK r9c when build shared library

And I integrate JsonCpp in my project, include the amalgamated source (a single .cpp file and two .h files), build a shared library like this:
Android.mk:

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE    := JsonCpp
LOCAL_CPPFLAGS := -fexceptions
LOCAL_SRC_FILES := jsoncpp.cpp
LOCAL_C_INCLUDES := $(LOCAL_PATH)/..\
$(LOCAL_PATH)/json 
LOCAL_EXPORT_CPPFLAGS := -I$(LOCAL_PATH)/json
LOCAL_LDLIBS    += -llog
include $(BUILD_SHARED_LIBRARY)

Use the shared library like this:

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE    := JsonTest
LOCAL_SRC_FILES :=  JsonTest.cpp
LOCAL_SHARED_LIBRARIES := JsonCpp
LOCAL_LDLIBS    += -llog
LOCAL_LDLIBS    += -landroid
include $(BUILD_SHARED_LIBRARY)

The test code is:

int ParseJsonFromString()
{
  const char* str = "{\"uploadid\": \"UP000000\",\"code\": 100,\"msg\": \"\",\"files\": \"\"}";

  Json::Reader reader;
  Json::Value root;
  if (reader.parse(str, root))
  {
    std::string upload_id = root["uploadid"].asString();
    int code = root["code"].asInt();
  }
  return 0;
}

But, If I build a static library, there is no segfault.

Interesting. But I won't be able to fix this myself. If someone submits a bug-fix, we're interested.

@liuhuixian Did you debug it more ? This program run fine normally, it seems some problem with your setup.
