Fun :)
Interesting too, I've _definitely_ got some code elsewhere, that's
usually compiled with clang

The stub_exe could segfault when built with some compilers (e.g. gcc
13.2.0), as SSE instructions which relied on stack alignment could be
generated, but the stack was misaligned.
This seems to be due to the __start entry point being run with a 16-byte
aligned stack, but the x86_64 SYSV ABI wantin
