--- Comment #1 from Mark Millard <markmi at dsl-only.net> ---
(In reply to Mark Millard from comment #0)
I tried a buildkernel via devel/amd64-gcc and its devel/amd64-binutils and
such.
It also gets notices like the example below:
ERROR: ctfconvert: die 23764: failed to get ref: No entry found
[dwarf_attrval_unsigned(177)]
This example is from:
--- aac_disk.o ---
Using built-in specs.
