libexpat 动态加载问题

linux9.0 用dlopen,动态加载函数XmlParse(),能成功被加载，但是访问core dump ,很是奇怪，错误点在memmove....,实在没有办法，只能直接连接到libexpat.so，直接用XmlParse而没有任何问题，很是奇怪
libexpat.dll在windows下动态加载无任何问题
所以只能改写：

NVXML_INLINE
2

bool NVXmlTree::Init_XmlLib(const char * libexpat){
3

#ifdef WIN32
4

if ( !_xml_dll.LoadDll(libexpat)){
5

return false;
6

}
7

_xmlf.XML_Parse= (NV_XML_Parse)_xml_dll.LoadSymbol("XML_Parse");
8

_xmlf.XML_ParserCreate = (NV_XML_ParserCreate)_xml_dll.LoadSymbol("XML_ParserCreate");
9

_xmlf.XML_ParserFree=(NV_XML_ParserFree)_xml_dll.LoadSymbol("XML_ParserFree");
10

_xmlf.XML_SetElementHandler=(NV_XML_SetElementHandler)_xml_dll.LoadSymbol("XML_SetElementHandler");
11

_xmlf.XML_SetUserData = (NV_XML_SetUserData)_xml_dll.LoadSymbol("XML_SetUserData");
12

_xmlf.XML_SetEncoding = (NV_XML_SetEncoding) _xml_dll.LoadSymbol("XML_SetEncoding");
13

_xmlf.XML_SetCharacterDataHandler = (NV_XML_SetCharacterDataHandler)
14

_xml_dll.LoadSymbol("XML_SetCharacterDataHandler");
15

#endif
16

#ifdef _UNIX
17

//-- on unix,using expat api directly
18

_xmlf.XML_Parse= (NV_XML_Parse)XML_Parse;
19

_xmlf.XML_ParserCreate = (NV_XML_ParserCreate)XML_ParserCreate;
20

_xmlf.XML_ParserFree=(NV_XML_ParserFree)XML_ParserFree;
21

_xmlf.XML_SetElementHandler=(NV_XML_SetElementHandler)XML_SetElementHandler;
22

_xmlf.XML_SetUserData = (NV_XML_SetUserData)XML_SetUserData;
23

_xmlf.XML_SetEncoding = (NV_XML_SetEncoding)XML_SetEncoding;
24

_xmlf.XML_SetCharacterDataHandler = (NV_XML_SetCharacterDataHandler)XML_SetCharacterDataHandler;
25

#endif
27

return true;
28

}
