Unable to reproduce in Linux with AMD Pro Drivers. I was able to reproduce it in Windows with an old build and 19.12.2 drivers. I rechecked with latest master and I wasn't able to reproduce it anymore. Can you recheck with the latest version?

Error   : EXCEPTION_ACCESS_VIOLATION
Address : 0x00007FF9E27C6CA9
Module  : C:\WINDOWS\System32\DriverStore\FileRepository\u0349464.inf_amd64_789f2a8b5b866ccf\B349558\amdocl64.dll

It crashes in the driver.

Can you recheck with the latest version?

Both scenarios mentioned still broken on latest version on builder at this point:
Broken: version: 2.82 (sub 6), branch: master, commit date: 2020-01-12 16:23, hash: rB0ef881cc5782

Not sure if useful, but tried it with latest 2.83 builder version and it is also broken:
Broken: version: 2.83 (sub 0), branch: master, commit date: 2020-01-14 06:12, hash: rB1bcb2bfd5724
