用NX Open C++画Studio Spline的访问冲突中断

我想用NX Open C++编个简单的外部程序生成一条Studio Spline曲线，直接用操作记录稍微改了一下。程序没有报错，但是调试的时候在“studioSplineBuilder1->CommitFeature()”这句（代码倒数第九行）跳出来这个中断：“***.exe 中的 0x2031f7eb 处未处理的异常: 0xC0000005: 读取位置 0x00000000 时发生访问冲突”(Unhandled exception at 0x2031f7eb in test.exe: 0xC0000005: Access violation reading location 0x00000000.)。请大牛指教。
我尝试过生成直线或圆弧，都没有这个问题。
我的邮箱：p36288@gmail.com，用的是NX7.0，中文Visual Studio 2008，系统WinXP。下面是程序原文：
