🐛 Bug

The version of protoc used by the CompilerGym build segfaults on macOS 12.0.1:

$ bazel-out/host/bin/external/com_github_protocolbuffers_protobuf/protoc
[1]    82656 segmentation fault  bazel-out/host/bin/external/com_github_protocolbuffers_protobuf/protoc

Thanks @mostafaelhoushi for discovering this!

To Reproduce

Steps to reproduce the behavior:

1. Update to macOS 12.0.1.
2. Start from a clean build: make distclean.
3. Attempt to build CompilerGym:

$ make install BAZEL_BUILD_OPTS='--sandbox_debug'
...
  /usr/bin/sandbox-exec -f /private/var/tmp/_bazel_cummins/c3f286fbbefcd6317d9b13e427e86632/sandbox/darwin-sandbox/3008/sandbox.sb /var/tmp/_bazel_cummins/install/97cf8d40e3de7fca7ef885fa763bde13/process-wrapper '--timeout=0' '--kill_delay=15' bazel-out/host/bin/external/com_github_protocolbuffers_protobuf/protoc '--python_out=bazel-out/host/bin/external/com_github_protocolbuffers_protobuf/python' -Iexternal/com_github_protocolbuffers_protobuf/python -Ibazel-out/host/bin/external/com_github_protocolbuffers_protobuf/python bazel-out/host/bin/external/com_github_protocolbuffers_protobuf/python/google/protobuf/timestamp.proto) sandbox-exec failed: error executing command
