Commit a87938b2e was included in 3.19.0-20.20 (see commit b51621abbcb4694b8d2842ce3a66006a60bba6e5), so perhaps trying this would be the first step to see if that commit fixes things. As it stands, I've checked the heap and stack on a VM image using this kernel and there is now plenty of space for the stack and heap.

The stack trace below shows the segfault actually occurs in libxml's xpath evaluation functions. I see no difference between xpath.c in upstream 2.9.2 and Ubuntu's version.
