Hey,

Any progress on it?

I just stumbled on it when debugging an AARCH64 target [0] run via QEMU user
emulation [1]. I wonder if that it is a bug in the QEMU user emulation layer
here or if comes from GDB?

https://github.com/perfectblue/ctf-writeups/tree/master/2019/insomnihack-te=
aser-2019/nyanc/challenge
[1] Via command `qemu-aarch64 -g 1234 ./nyanc`, but I first used patchelf to
set interpreter and libc:
```
patchelf --set-interpreter ./ld-linux-aarch64.so.1 ./nyanc=20
patchelf --replace-needed libc.so.6 ./libc.so.6 ./nyanc=20
```
