Description
The following Python program crashes for me under both Windows and Linux (showing a segmentation fault under Linux):
from saxonche import *
with PySaxonProcessor() as saxon_proc:
print(saxon_proc.version)
xdm_node = saxon_proc.parse_xml(xml_file_name='sample1.xml')
xdm_children_list = xdm_node.children
xdm_axis_nodes_children = xdm_node.axis_nodes(XdmNodeKind.CHILD)
print(len(xdm_children_list) == len(xdm_axis_nodes_children))
xdm_node1 = xdm_node.item_at(0)
xdm_axis_nodes_following_siblings = xdm_node1.axis_nodes(XdmNodeKind.FOLLOWING_SIBLING)
print(len(xdm_axis_nodes_following_siblings))

gdb output (not telling me something helpful but perhaps it helps to tell what is wrong):
