隨着macOS從10.12更新到10.13,/ usr/local/bin/bison停止工作。bison 3.0.4在非法指令中失敗:4在macOS上高Sierra 10.13
問題:
$ /usr/local/bin/bison --version
Illegal instruction: 4
重建野牛的嘗試也失敗並LLDB報告EXC_BAD_INSTRUCTION。

解決方法: 如果你使用Xcode的9,其gcc版本可能是蘋果LLVM 9.0.0版。通過將(defined __APPLE__ && __clang_major__ >= 9)
添加到野牛源文件中的#if宏來應用補丁。然後重建並重新安裝它。
