From dce1fae986f4f61f51e7825de903aa58239c28c8 Mon Sep 17 00:00:00 2001 From: Andrey Kleshchev Date: Thu, 23 Nov 2023 23:28:10 +0200 Subject: SL-17076 MacOS crash on clearing ChicletNotificationChannel Crash appears to happens inside mItems.clear() of the LLNotificationChannelBase, but there is no apparent reson for it and stack jumped some steps, so I'm doing cleanup more explicitly to see if it's indeed there and not a corruption somewhere earlier. --- indra/llui/llnotifications.cpp | 14 +++++++++++--- 1 file changed, 11 insertions(+), 3 deletions(-) (limited to 'indra/llui/llnotifications.cpp') diff --git a/indra/llui/llnotifications.cpp b/indra/llui/llnotifications.cpp index d736aa6634..c0a7866926 100644 --- a/indra/llui/llnotifications.cpp +++ b/indra/llui/llnotifications.cpp @@ -1171,6 +1171,14 @@ LLNotificationChannel::LLNotificationChannel(const std::string& name, connectToChannel(parent);
