protoc segfaults on macOS 12 Beta if built with bazel #8884
Description
Hi!
I'm using protobuf as a Bazel dependency in my project and since upgrading to macOS Monterey Beta protoc has started segfaulting.
I'm running macOS Monterey 12.0 Beta (21A5304g), x86_64, with Command Line Tools for Xcode 13 beta 5 and Bazel 4.1.0.
Steps to reproduce:
- clone this repo
bazel build //:protoc./bazel-bin/protoc- it crashes with
Segmentation fault (11)instead of printing the usage screen. Needless to say, invoking it with real arguments crashes as well.
I've tried building it with autotools and it works just fine, so I assume it's something with the compiler/linker options in Bazel that breaks things. Unfortunately, my clang-fu is not nearly strong enough to figure out the cause myself.
Here's the backtrace from lldb:
$ lldb ./bazel-bin/protoc
