> There is an assertion failure with this code:
> -----------------------<cut>-------------------------<
> #include <xalanc/XalanTransformer/XalanTransformer.hpp>
> #include <xalanc/XalanDOM/XalanDOMString.hpp>
> XALAN_USING(XALAN_CPP_NAMESPACE, XalanDOMString)
> int main(void) {
> XALAN_USING_XERCES(XMLPlatformUtils)
> XALAN_USING_XALAN(XalanTransformer)
> XMLPlatformUtils::Initialize();
> XalanTransformer::initialize();
> XalanDOMString a("xxxxxxxxxxx"), b;
> a.substr(b); //the same as a.substr(b, 0,
> XalanDOMString::npos);
> return 0;
> }
> -----------------------<cut>-------------------------<
> Here goes the output:
> -----------------------<cut>-------------------------<
> Assertion failed: thePosition < theSource.size() && thePosition + theCount
> <= theSource.size(), file
> /u02/home/avinokur/xalan-c/xml-xalan/c/src/xalanc/XalanDOM/XalanDOMString.cp
> p, line 224
> Abort (core dumped)
> -----------------------<cut>-------------------------<
> As I've found the assertion fails in "thePosition + theCount <=
> theSource.size()" code, computing it to "0 + 4294967295 <= 11". Trying
> "a.substr(b, 1)", the condition will be "1 + 4294967295 <= 11" which is "0 <
> 11" due to "typedef unsigned int size_type;" code from
> ``xalanc/XalanDOM/XalanDOMString.hpp''.
