This is odd. Works on my laptop, TEST pauth-1 on aarch64 TEST pauth-2 on aarch64 TEST pauth-4 on aarch64 TEST pauth-5 on aarch64 TEST bti-1 on aarch64 TEST bti-2 on aarch64 TEST semihosting on aarch64 However, this crashes on an aarch64 host. Looking at the trace, the compiler generated bad code -- the difference of two symbols resulted in 0. So we never copied the test code to the mmaped page. I assume your x86_64 build is using the docker images for cross-compile? I wonder if my laptop is picking up a local cross-compiler instead. And then the aarch64 host compiler has the same problem as the docker version? r~
