I did find an issue on the rust GH repo [0], and it seems this also affects the nix-rust project, who seem to have the same errors as our currently failing build [1]. A temporary workaround could be to have a custom version of jemalloc with the c++ features disabled by building with `--disable-cxx'. Alternatively, we could just make use of jemalloc 4.5.0 for rustc only until this is all sorted our by upstream.
