RE: Deleting char* returned from DOMString.transcode() in VC++ 6.0

Title: Deleting char* returned from DOMString.transcode() in VC++ 6.0

         To Dave and Jesse;

Just another caviot to this ongoing sogga -

 

the comment inside of dbgheap.c where the Assertion fails says the following:

 

        /*
         * If this ASSERT fails, a bad pointer has been passed in. It may be
         * totally bogus, or it may have been allocated from another heap.
         * The pointer MUST come from the 'local' heap.
         */       
        _ASSERTE(_CrtIsValidHeapPointer(pUserData));

Like I said; this maybe just a Microsoft quark.

In addition to Jesse's reply to this message, you should use:

    delete [] Name;

Jesse;

 

Thanks for the tip.  I am linking to the xerces_c_1D.lib and I have the xerces_c_1_4D.dll in my path.  Upon recompile/link of my

program I got the following error message during the run:

 

    Debug Assertion Failed!

 

    Program: D:\MyDevArea\XGateWayTest\Debug\XGateWayTest.exe

    File: dbgheap.c

    Line: 1044

   

    Expression: _CrtIsValidHeapPointer(pUserData)

                        .

                        .

                        .

 

the code that generated this is the following:

 

       
        Name = (char*)item.getNodeName().transcode();

 

        nodeName.assign( Name );

 

        delete Name;

 

//        DOMString::transcodeDelete(Name);

 

The moment the delete Name; line is executed the above error is generated.

 

If I comment the delete Name; line and uncomment the DOMString::transcodeDelete(Name); line

which I added locally to the Xerces library, then it runs fine.
