title: Fatal signal 11 (SIGSEGV), code 2, fault addr 0x74446000 in tid 13424 (GLThread 785)
body: <p>I'm getting this error Fatal signal 11 (SIGSEGV), code 2, fault addr 0x74446000 in tid 13424 (GLThread 785) when I run in Nexus 9.
  But other cellphone doesn't crash(HTC Butterfly2,Samsung note3).
  When I run in Debug,it run in gl.glDrawArrays(GL10.GL_TRIANGLES,0,vCount); will crash.</p>
  
  <p>Here is my code </p>
  
  <pre><code>public void drawSelf(GL10 gl)
  {
      gl.glRotatef(mAngleZ, 0, 0, 1);
      gl.glRotatef(mAngleX, 1, 0, 0);
      gl.glRotatef(mAngleY, 0, 1, 0);
  
      //允許使用頂點陣列
      gl.glEnableClientState(GL10.GL_VERTEX_ARRAY);
  
      gl.glVertexPointer
      (
              3,              
              GL10.GL_FIXED,  
              0,              
              mVertexBuffer   
      );
      mVertexBuffer.rewind();
  
  
      gl.glEnableClientState(GL10.GL_NORMAL_ARRAY);
  
      gl.glNormalPointer(GL10.GL_FIXED, 0, mNormalBuffer);
      mNormalBuffer.rewind();
      gl.glDisable(GL10.GL_TEXTURE_2D);     
      gl.glDisable(GL10.GL_TEXTURE_COORD_ARRAY); 
  
      gl.glEnable(GL10.GL_TEXTURE_2D);   
  
      gl.glEnableClientState(GL10.GL_TEXTURE_COORD_ARRAY);
  
      gl.glTexCoordPointer(2, GL10.GL_FLOAT, 0, mTextureBuffer);
      mTextureBuffer.rewind();
  
      gl.glBindTexture(GL10.GL_TEXTURE_2D, texId);
  
      gl.glDrawArrays(GL10.GL_TRIANGLES,0,vCount);
  
  }
