So then this can be considered a libxml2 bug then?

xmlRealloc() passes through to xmlReallocLoc()

xmlReallocLoc(void *ptr,size_t size, const char * file, int line)
{
MEMHDR *p;
unsigned long number;
if (!xmlMemInitialized) xmlInitMemory();
if (ptr == NULL)
return(NULL);
.....

it bombs out at if(ptr == NULL)
