their ability to connect their Windbg debugger to gdbserver running on a
remote machine through WSL. I have been trying to experiment with that. I
ssh into a linux machine through WSL. When I try to connect using Windbg,
the connection is successfully established but gdbserver dies with:

../../gdbserver/regcache.cc:271: A problem internal to GDBserver has been
detected.
Unknown register ymm0h requested

A bit of searching on the interwebs revealed this to be a problem with a
particular version of gdbserver (< 7.0) but I am running the latest (14.2),
so it probably isn't a version issue.

Interestingly I am successfully able to connect from yet another linux
machine from gdb to gdbserver just fine.

Any ideas on why or how this might have happened?
