Looking at recently committed 2e616dee9e60, we have introduced this:
+ volatile xmlBufferPtr buf = NULL;
+ volatile xmlNodePtr cur_copy = NULL;
where the pointer-ness nature of the object is inside the typedef. I
*suppose* that this is correct as written. There are a few occurrences
of this pattern in eg. contrib/xml2.
