Steps To Reproduce:
1) Install the MDA VST's from http://mda.smartelectronix.com/ 2) Create some mono or stereo audio. Mono seems more likely to reproduce the problem. 3) Open mda Tracker 4 )Press "Start Playback" then "Apply". 5) Audible playback should cease but the Play button should still be depressed and the meters still be active. 6) Press "Close". 7) Observe: Audacity should now crash. 8) If not, press SPACE to play and if necessary SPACE to stop.

Regression on 2.0.6 in that there is no crash in use there.

I can't reproduce this.  I suspect that:

https://github.com/audacity/audacity/commit/7414b000c264becd7a47279c123a6f7308eff8f0

probably fixed it since the are REALLY REALLY old VSTs and the version check in that commit would have been important.

I can still 100% reproduce the bug in Windows 10 in 2.1.0, 2.1.1 (after your commit above) and HEAD.

This really should not be considered an Audacity problem - it is a problem for the plug-in developer.

I don't agree that Audacity crashes should be considered "somebody else's problem". Other audio editors manage to survive bad plug-ins without crashing.

Audacity shouldn't be so brittle imo, especially for plug-ins that work in other applications. Audacity's support for 3rd party plug-ins is not good (LV2 support on Linux is terrible).

Testing on W10 with audacity-2.3.3-alpha-271-d84ab5948d544eec6ba6a648d76d31ef9d5edc88

mda Tracker still crashes Audacity (with both mono and stereo) - but earlier than in Gales steps:

For me at crashes at Step 4 -    "Start Playback" then "Apply" => crash

But also "Start Playback" then "Stop Playback" => crash


Curiously it's just the RTP that fails - just using "Apply" directly does not crash and does apply the effect - modified the title to show RTP nature of the bug

Downgrading this to P4 - we really do not need to clutter the Release Notes with listings of 3rd party plugins that fall to work or crash Audacity.

a) they are curated in Bugzilla via superbug Bug #665

b) they are listed in the Wiki on this page: https://wiki.audacityteam.org/wiki/Plug-ins_that_crash_Audacity_or_fail_to_work_properly_in_Audacity

c) that Wiki page is now linked to from the main Wiki>Plug-ins page
https://wiki.audacityteam.org/wiki/Plug-ins

d) the page in b) above is now linked to from each of the three platform pages for installing plug-ins:
https://alphamanual.audacityteam.org/man/Installing_Effect,_Generator_and_Analyzer_plug-ins_on_Windows
similarly for Mac and Linux

I think that is sufficient documentation of them without cluttering the Release Notes
