What system did you try building on? And which rustc version did you use?

Is it rustc that segfaults or a build script?

Can you run that command in gdb to get a backtrace?

alexcrichton commented on issue #10406:

Is this using rustc_codegen_cranelift to build Cranelift? If so this issue probably belong on rustc_codegen_cranelift. If it's a general segfault compiling Rust code then this probably belongs on the rust-lang/rust issue tracker.

bjorn3 commented on issue #10406:

I don't think it uses cg_clif. The failing command contains neither rustc-clif nor -Zcodegen-backend. In any case I did be highly surprised if Termux were to ship cg_clif, especially on a stable rustc version.

I'm trying to mostly clarify what to do with this issue on this repository. I don't know what termux is for example and the actual OP of this issue is pretty light on details (and didn't actually fill out most of the template, just used the default values). Is this something expected to be fixed in this repository?
