From 335409248ea932e93ce4361564b8e92d0b83b071 Mon Sep 17 00:00:00 2001 From: Maria Matejka Date: Thu, 20 Apr 2023 19:33:00 +0200 Subject: [PATCH] Linpool: Fix lp_restore() When lp_save() is called on an empty linpool, then some allocation is done, then lp_restore() is called, the linpool is restored but the used chunks are inaccessible.
