Tue, 14 Dec 2021 08:48:05 +0100Variable forcing now uses limited list and buffer instead of systematical instance tree traversal and in-tree "fvalue" to keep track of forced value for pointed variables (external, located). Pointer swapping is performed when forcing externals and located, with backup being restored when forcing is reset. Match Beremiz commit 93ad018fb602.

used as argument for function block, for example) and this is not
fixed for a long time.
