Turns out that the libxml2 package maintainer found the issue and put it in bz 644312. 
For anyone else looking, the patch is something like this:

diff --git a/xmlschemas.c b/xmlschemas.c
index e0d3b7a..3baae05 100644
--- a/xmlschemas.c
+++ b/xmlschemas.c
@@ -22197,7 +22197,7 @@ xmlSchemaXPathEvaluate(xmlSchemaValidCtxtPtr vctxt,
                    "allocating the state object history", NULL);
                return(-1);
            }
-           sto->sizeHistory = 10;
+           sto->sizeHistory = 5;
        } else if (sto->sizeHistory <= sto->nbHistory) {
            sto->sizeHistory *= 2;
            sto->history = (int *) xmlRealloc(sto->history,

There will be a libxml2 errata in the 5.7 update taking care of this.
