I'm sorry, during  the init, 

void SphereSurf::genBezelDisk(float r, float a1, float a2, float a3, int nsNums, int ewNums)
{
    //float h0 = r * cosf(a1);
    int num1, num2, num3;
    pEWTbl = new float[2 * ewNums]; // should be adjust to new float[2 * ewNums + 2]
    float dFai = 2.f*3.1415926f / (float)ewNums;
    for (int i = 0; i <= ewNums; i++) { ///write beyond the buffer
        pEWTbl[2 * i] = cos(dFai * i);
        pEWTbl[2 * i + 1] = sin(dFai * i);
    }
    ....
}
after rewrite the function, eglDestroyContext would not corrupted
