I suppose this is needed because array-view.h uses gdb_assert, and you
noticed it because some files didn't compile, because they didn't
happen to include gdb_assert.h before array-view.h.

I think it could be const:

gdb::array_view<const gdb_byte>

And the other overload of bytes_to_string too.

Otherwise:
