There is a string copy bug in HostAttributeList::getString. The bug also exists in 3.7.1 that was recently released.
This was causing many plugins such as Console One, Waves CLA Mix Hub or iZotope Neutron to display garbage in channel names when they query for attributes in response to Vst::ChannelContext::IInfoListener. Any DAW using Vst::ChannelContext::IInfoListener::setChannelContextInfos will break due to this.
I’ve submitted a pull request for the same.
