Bug ID: 28635
Summary: regcache.cc:257: A problem internal to GDBserver has
been detected. Unknown register zmm16h requested
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: server
Assignee: unassigned at sourceware dot org
Reporter: vries at gcc dot gnu.org
Target Milestone: ---
I'm running into:
...
FAIL: gdb.server/connect-with-no-symbol-file.exp: sysroot=: action=permission:
connection to GDBserver succeeded (the program is no longer running)
FAIL: gdb.server/connect-with-no-symbol-file.exp: sysroot=target::
action=permission: connection to GDBserver succeeded (the program is no longer
running)
...
The first FAIL in more detail:

When recreating on the command line, we get a bit more info:
