Since `683da41`, I’m no longer able to build Julia from master (on linux or macOS)

```julia
Compiling the compiler. This may take several minutes ...
Base.Compiler ──── 177.213 seconds
flparse.jl
    JULIA usr/lib/julia/sys.ji
Aborted (core dumped)
***This error might be fixed by running `make clean`. If the error persists, try `make cleanall`.***
make[1]: *** [sysimage.mk:72: /home/chris/julia.git/usr/lib/julia/sys.ji] Error 1
make: *** [Makefile:114: julia-sysimg-ji] Error 2

```

Any ideas?

I’ve also been seeing this which is very odd since CI seems unaffected

Did you try to run `make cleanall`?

On CI the build starts from a clean state.

In such cases one option is to do `git status --ignored`, to see all files and directories ignored by Git. One of them must be the culprit, so delete away.

It fails after a fresh clone

I think this probably has to do with compiler versions or something, but I don’t know how yet

This should probably be an issue

Works for me on

- aarch64-darwin with Apple Clang 15
- aarch64-linux with GCC 11.4
- x86\_64-linux with GCC 11.4 and GCC 14.2

Can you show your ENV? It’s fascinating that it fails for you on both platforms both being completely different.

Also, do you have a `Make.user` file?

The mac environment is minimal, with only `PATH` standing out as potentially interesting

```julia
PATH=/usr/local/bin:/System/Cryptexes/App/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/local/bin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/bin:/var/run/com.apple.security.cryptexd/codex.system/bootstrap/usr/appleinternal/bin:/Library/Apple/usr/bin

```

On both machines, I’m able to successfully build `master` in a `gcc` docker container (ie, `docker run -it gcc`), which happens to have gcc 14.2

Do you have JULIA\_NUM\_THREADS set as an envar. We identified a bug when building julia with that set.

[Building Julia segfaults when `JULIA_NUM_THREADS=4,1` is set · Issue #56533 · JuliaLang/julia · GitHub](https://github.com/JuliaLang/julia/issues/56533) tracks this. @gbaraldi and I think that the threading is the cause. To confirm, can you run `JULIA_NUM_THREADS=1 make` and make sure that works?

Yup, that’s it
