---------------------------------------
Summary: XalanVector assignment operator crash bug
Key: XALANC-742
URL: https://issues.apache.org/jira/browse/XALANC-742
Project: XalanC
Issue Type: Bug
Components: XalanC
Affects Versions: 1.11, CurrentCVS
Environment: Tested on Windows 7 and RHEL5
Reporter: Michael Chisholm
Assignee: Steven J. Hathaway
Priority: Critical
When assigning an empty XalanVector to another, a NULL dereference and crash
results. Specifically, the std::copy() statement copies to this->begin(),
which returns NULL when the vector is empty.
Here is simple demo code:
#include <xercesc/util/PlatformUtils.hpp>
#include <xalanc/Include/XalanVector.hpp>
using namespace xercesc;
using namespace xalanc;
int main(int argc, char* argv[])
{
XMLPlatformUtils::Initialize();
XalanVector<int> vec1;
XalanVector<int> vec2(XalanMemMgrs::getDefaultXercesMemMgr(), 5);
vec1 = vec2;
XMLPlatformUtils::Terminate();
return 0;
}
