It's probably a data race. AArch64's memory model is much more relaxed than that of x86-64, so data races are much more likely to lead to errors. Additionally, while on x86 interlocked* routines implicitly act as memory barriers between them (due to an architectural idiosyncrasy), they don't on any other architecture.
