Cannot build the toy language example with bazel

[tisonkun]

Reproduce

The reproduce is simple, with file structure:

toy/
toy/BUILD
toy/MODULE.bazel
toy/WORKSPACE
toy/toy.cpp

where

1. toy.cpp contains the example code
2. WORKSPACE is empty.
3. BUILD contains:

cc_binary(
  name = "toy",
  srcs = ["toy.cpp"],
  deps = [
    "@org_llvm_project//llvm:Core",
    "@org_llvm_project//llvm:Support",
  ]
)

4. MODULE.bazel contains:

module(name = "toy", version = "0.1.0")
bazel_dep(name = "llvm-project", version = "17.0.3", repo_name = "org_llvm_project")

when build with:

$ bazel build --enable_bzlmod --action_env=BAZEL_CXXOPTS="-std=c++17" --sandbox_debug --verbose_failures //:toy

it fails with:

INFO: Analyzed target //:toy (58 packages loaded, 1490 targets configured).

while if built with:

$ clang++ -g -O3 toy.cpp `llvm-config --cxxflags --ldflags --system-libs --libs core` -o toy

It succeeds with preinstalled LLVM@17.

It seems a script returns value other than 0. I tried to debug and get:
