OpenVDB Grid.h segfaulting when checking tree type

[Kalina]

I am trying to resurrect an old version of a Houdini plugin that no longer works with newer versions of Houdini. I've tracked down the issue to a segfault happening in the file $HFS/toolkit/include/openvdb/Grid.h , where the function Grid<TreeT>::setTree(TreeBase::Ptr tree) is checking the type of the tree:

tree->type()

I can't figure out what could be causing this to segfault. When I print ouf the tree details with tree->print(std::cout, 4) I see that the tree type is "Tree_float_5_4_3", which seems fine? So why would this cause an issue? Anyone have any ideas?

The full print output is:
