Hello,
I'm not sure if this is the best place to post this, but I ran the conformance test software from my build of Wine on Ubuntu 16.04 and it crashed the OS. I have Ubuntu 16.04 in VirtualBox, hosted by Windows 10.
I ran the following in my wine64 folder, as found on the page wiki.winehq.org/Conformance_Tests:
wine ./programs/winetest/winetest.exe.so
At about 8 minutes into the test the screen went black. I waited for a few minutes to see if it would come out of that state, but it did not. I had to kill the whole OS.
I've never run a conformance test for Wine before.
Thanks for any feedback!
...John
