I am running:

# uname -apKU
FreeBSD FBSDFSSD 13.0-CURRENT FreeBSD 13.0-CURRENT #9 r343884M: Thu Feb  7 
19:22:33 PST 2019 
markmi@FBSDFSSD:/usr/obj/amd64_clang/amd64.amd64/usr/src/amd64.amd64/sys/GENERIC-NODBG
  amd64 amd64 1300010 1300010

but I happen to have been booting the SSD via Hyper-V under Windows 10 Pro
instead of directly in recent times. (Things are configured to allow booting
from the BIOS as well.) Also: My builds are normally with non-debug kernels,
the above included.

I'm not seeing any problems with booting in my context.

But I've been running various FreeBSD versions based on clang 7
for a while. Currently:

# clang -v
FreeBSD clang version 7.0.1 (tags/RELEASE_701/final 349250) (based on LLVM 
7.0.1)
Target: x86_64-unknown-freebsd13.0
Thread model: posix
InstalledDir: /usr/bin

I'd not expect clang vintage to be the issue.

This is after deleting /usr/obj, and cleaning the ccache cache. All  
cases are with CPUTYPE=native (Intel Xeon E5620).


I remember a commit of a new clang to head. Anything else in the  
area of influence for this?
My next try is to compile without CPUTYPE=native to see if the new  
clang is doing something in this area which it didn't do before. Has  
anyone else seen a similar issue or has an idea what to look at next?


Removing the CPUTYPE setting in make.conf didn't help. Ideas welcome.

Bye,
Alexander.
