From d1b8074ffe4b945a41e3ad9e1fb43332d78d73fb Mon Sep 17 00:00:00 2001 From: Markus Mohrhard Date: Mon, 9 Jan 2017 05:58:00 +0100 Subject: tdf#104830, need an own termination listener for lib objects The destruction of the SwDLL object happens already through the normal termination listener but the other termination listeners might still depend on it. Also the outstanding events might need the SwDLL instance to be still around. This makes the destruction of the instance explicit and at a time when it should be safe. We should use the same code for calc, impress, math and base as well.
