That’s a really good question!
I guess one way to narrow it down is what’s the linker implementation on
each env? I think you can arrange to use the same ld impl on bsd and Linux
if you want, since both are elf platforms. Are they both doing dynamic or
static linking? Are they using the same Ld implementation? It’s certainly
strange to have there be a difference in behavior between two x64 elf
