When attempting to perform the clone syscall, an error of -1 is returned where I would expect it to succeed. Running the same executable outside of qemu works as expected. -Steps to reproduce: -1. gcc clone.c -2. qemu-x86_64 a.out -Additional information: -I've tried building with gcc, zig cc, and clang and the output of each works fine when running natively, but running under qemu fails.
