From 95fad99cb28e9970944b01fd7af452f6f9f37484 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Volker=20R=C3=BCmelin?= Date: Tue, 24 Mar 2020 07:18:55 +0100 Subject: [PATCH] hw/audio/fmopl: fix segmentation fault MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Current code allocates the memory for ENV_CURVE too late. Move allocation to OPLOpenTable() and deallocation to OPLCloseTable(). To reproduce the bug start qemu with -soundhw adlib.
