Problem with xercesc_2_6::XMemory::operator
Well it seems that a problem never comes alone.
There seems to be a problem in my program hat is
causing me some trouble. I'm using a sax parser but i
get a seg fault when i run the program.
Here is the output of gdb
Starting program:
/home/david/Actigenics/libs/C++/base/XmlXercesFactory/SaxParsing_classtest
-e ISO8859-1 config.pubmed snorna_cancer

##############################
My Xml.h class is as follows
###############################
This implementation gives a segfault
class Xml : public DefaultHandler, public
XMLFormatTarget {
If i use this one below it works
//class Xml : public DefaultHandler {
public:
Xml();
virtual ~Xml();
########classtest
line 194
XmlFactory xmlf(c_v ,c_d ,c_n ,c_s ,c_fs ,c_e);
Xml *parser = xmlf.setParser(type);
...
As you can see one declaration is working and the
other not. That is the only difference.
Any idea ???

Yep,
I have implemented an internal function to do that.
the program runs properly if I use the
class Xml : public DefaultHandler
instead of the
class Xml : public DefaultHandler , public
XMLFormatTarget
All the abstracts function are set and i can parse the
xml file as i want. It is just when i implement the
XMLFormatTarget that it crashes...
void Xml::_init()
{
try {
XMLPlatformUtils::Initialize();
}
catch (const XMLException& e) {
std::cout << "Error during initialization! :\n"
<< Error(e.getMessage()) << "\n";
exit(-1);
}
//std::cout << "Xml platform initiated" <<
std::endl;
}
void Xml::_destruct()
{
XMLPlatformUtils::Terminate();
//std::cout << "Xml platform terminated" <<
std::endl;
}

Hi David,
have you called XMLPlatforUtils::Initialize()?
