emulators/virtualbox-ose: guest machines are no longer usable: Failed to construct device 'VMMDev' instance #0 (VERR_INTERNAL_ERROR_3)

[vvd]

Summary

1. llvm10 in FreeBSD before r364284 miscompiles virtualbox 6.1 causing errors.
2. llvm15 in FreeBSD miscompiles virtualbox 6.1 causing errors: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=270189.

Force llvm14 from ports. Use VBOX_LLVM_VER in make.conf to define different llvm.

Tested build on 12.4, 13.1, 13.2, but I don't have 14 for test build and run.

What's the rationale for patches? They look strange.

14.0

If not patched, then guest machines are unusable. Visually, from https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=270189#c82:

[vvd]

We have not found confirmation of the need for new patches.

I will test on 14-CURRENT this weekend. The patch has been applied, packages built on my poudriere, and machines updated. I won't have time until Saturday or Sunday to test because the machine that will be used to run the test is busy with other work ATM.

https://www.freshports.org/emulators/virtualbox-ose/#history is currently at 6.1.44_1.

https://docs.freebsd.org/en/books/porters-handbook/book/#makefile-naming-revepoch – if I understand correctly, D40254 should bump the PORTREVISION from 1 to 2 at line 3.

Tested and works on a recent 14-CURRENT.

Also, re: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=270189#c118 we have recent history https://reviews.freebsd.org/source/ports/history/main/emulators/virtualbox-ose/ that requires changes to the patch.
