From 1aacab49ea0e5cff94bd89595737b6af677f4490 Mon Sep 17 00:00:00 2001 From: Jan Edmund Lazo Date: Sun, 5 Jan 2020 10:40:02 -0500 Subject: vim-patch:8.1.1579: dict and list could be GC'ed while displaying error Problem: Dict and list could be GC'ed while displaying error in a timer. (Yasuhiro Matsumoto) Solution: Block garbage collection when executing a timer. Add test_garbagecollect_soon(). Add "no_wait_return" to test_override().
