Proposed patch
I managed to get a working qemu setup without much efforts using
Buildroot, and I can reproduce the issue. Although if there is a ready-
to-use Ubuntu image I can use, I'd be happy to use it (I just don't want
to go through the trouble of installing the distro in qemu with the
installer).
See the attached patch, it does fix the issue for me.
However, the inferior always hits this when running:
Program received signal SIGSEGV, Segmentation fault.
0x000003ffac312c6c in _dl_debug_initialize () from /lib/ld64.so.1
... and that was happening prior to my patches, and in GDB 10. I guess
you don't see it?
