The Rust linker (rust-lld) is crashing with a bus error (signal 7) during the linking phase of test compilation in GitHub Actions CI. The crash is intermittent and does not occur in local development environments. Environment:
- OS: Linux (GitHub Actions runner: ubuntu-latest)
- Rust version: Stable (latest from rustup)
- Toolchain: stable-x86_64-unknown-linux-gnu
- Project: Rust workspace with multiple crates
- Linker: rust-lld (bundled with rustc)
Error Output:
```
collect2: fatal error: ld terminated with signal 7 [Bus error], core dumped
compilation terminated.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
```
Steps to Reproduce:
1. Run cargo test --workspace in CI environment (GitHub Actions)
2. Error occurs during linking phase of integration tests
3. Specifically fails while linking test binaries with feature flag --cfg 'feature="full"'
Expected Behavior: Tests should compile and link successfully (as they do locally). Actual Behavior: Linker crashes with signal 7 (SIGBUS - Bus error), indicating a hardware/memory fault. Additional Context:
- All 544+ tests pass successfully on local Windows and Linux machines
- cargo build --release succeeds locally
- The crash is non-deterministic (re-running sometimes succeeds)
- This appears to be a CI infrastructure issue rather than code-related
- Error occurs during test binary linking, not during compilation or test execution
