Using the AudioPluginHost off the tip of develop, if you trigger a scan for LV2 plugins, you get a mem leak at shutdown: Detected memory leaks! Dumping objects -> {8110} normal block at 0x0000024970AE5EC0, 39 bytes long. Data: <%APPDATA%\LV2;%C> 25 41 50 50 44 41 54 41 25 5C 4C 56 32 3B 25 43 Object dump complete. The program '[24484] AudioPluginHost.exe' has exited with code 0 (0x0). FWIW, I have no LV2 plugins installed - was just curious about it!
