cargo crashes with SIGSEGV on macOS with rosetta

[joelkraehemann]

Hi,

I have 2 custom rustc and cargo-c installation on macOS, one for arm64 and another for x86_64 with rosetta.

Now I try to build librsvg but cargo invoked by meson crashes with SIGSEGV.

https://gist.github.com/joelkraehemann/5630888dca0b3541afae257d1e88c7a2

Here is my terminal output:

Can you please reduce it to a single cargo-c command?

[joelkraehemann]

Hi @lu-zero

It is in the log:

[lu-zero]

running it in isolation still brings the same problem? I'm trying to understand what went wrong and if it is simple to add it to the CI so we won't trip in the same situation :)

[sdroege]

The problem here seems to be specific to running cargo-c (or probably anything using clap or so?) through rosetta (i.e. amd64 binary running on arm64 macOS). cargo-c works fine natively on both amd64 and arm64.

[joelkraehemann]

Yes, exactly. Run shell as x86_64 on aarch64.

/usr/bin/arch -x86_64 /bin/bash

and check current arch:

uname -pm

This gives you: x86_64 i386

As workaround I use aarch64 to cross compile to x86_64. So I am not blocked. Check gist link above to reproduce.

Here is my cross build:

just to be sure, if you try to run a tiny clap based program sporting the same options crashes similarly?

Sorry, I don't know any rust. Just wanted to build librsvg with rosetta.

[lu-zero]

It is very fringe and from the backtrace seems a problem with clap.

[sdroege]

That function in clap is not doing anything special btw, so it's more likely a problem with something more fundamental in std when running via rosetta. But only someone with suitable Apple hardware will be able to debug this.
