R6030- CRT not initialized

vs2010 debug下调试c 程序报错：

Runtime Error! Program: D:\Program Files (x86)\test\test\test.exe R6030 - CRT not initialized

参考https://blog.csdn.net/chenlycly/article/details/12087146介绍，使用windgb查到

//...

发现exe引用的的libcurl.dll是release于是重新编译了一个版本debug版本，覆盖release版的libcurl.dll再次调试后发现不报告CRT not initialized错误了。

总结：1.windbg是好东西，可以定位加载到哪里dll失败；2.如果在程序中混合msvcr100.dll和msvcr100d.dll可能会造成CRT not initialized错误。
