+commit d7958b21e7f8c447a26bb2436f08402b2c308be4
+Author: Chris Evans <scarybeasts@gmail.com>

+
+ Fix some potential problems on reallocation failures
+
+ The count was incremented before the allocation
+ and not fixed in case of failure
+ * xpath.c: corrects a few instances where the available count of some
+ structure is updated before we know the allocation actually
+ succeeds
