It worked just fine before upgrading to Julia 1.6.0. Now when I try to use compile\_app it gives a segfault part way through. It doesn’t crash, but I haven’t tried waiting long after the segfault.
```julia
[westly08:06~]$ julia -q --project
julia> using PackageCompiler
julia> create_app("EPUBCreate", "EPUBCreate-linux-aarch64-bin")

It’s always had that dependency error and worked fine before.

I’m seeing the same with Julia 1.7.x as well as nightly releases. Did you manage to work around this?

Late reply, but on what specific AArch64 CPUs is this? I’ve noticed this only on NVIDIA ARM CPUs, and filed [https://github.com/JuliaLang/julia/issues/41852](https://github.com/JuliaLang/julia/issues/41852).

Yup. I’m seeing this on nVidia TX2 ARM CPU.
