Michael Chisholm updated XALANC-742:
------------------------------------

    Environment: Tested on Windows 7  (was: Tested on Windows 7 and RHEL5)
    
> 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: CurrentCVS, 1.11
>         Environment: Tested on Windows 7
>            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;
> }
