The bug is in xmlXPathNodeValHash. `string` must be reset to NULL in the 
default case of this switch statement:

    https://git.gnome.org/browse/libxml2/tree/xpath.c#n6412

The bug can only be triggered if there are multiple descendant text nodes and 
the first one only contains a single character. The handling of comment and PI 
nodes in the switch statement also looks fishy.

I'll commit a fix after the 2.9.6 release.
