If anyone has any objections, please let me know. ------------------ From: Konstantin Komarov [ Upstream commit 194491be54e1c9e4d29d3ee777b05ff031c4b670 ] When popping a level from the index lookup stack, indx_find_sort() frees the struct indx_node but not the index buffer it owns. Every call that descends and then pops a level leaks that allocation. Free n->index before freeing the node itself.
