【标题描述】使用clang编译器编译pymol软件的时候报错。
报错信息如下：clang-12: error: clang frontend command failed with exit code 139

【环境信息】
硬件信息：
1）Kunpeng-920处理器 CPU：96core
软件信息：
1） openEuler 20.03 (LTS-SP3)
2） uname -r：4.19.90
3） pymol-open-source-2.5.0
4） Python 3.8.2
5） BiSheng Compiler 2.1.0.B010 clang version 12.0.0

【问题复现步骤】
1）安装pymol依赖项
2）编译pymol
cd pymol-open-source-2.5.0
python3 setup.py build install --prefix=/opt/pymol

【出现概率(是否必现，概率性错误)】
问题必现

【预期结果】
执行命令python3 setup.py build install --prefix=/opt/pymol后会在/opt/pymol目录下生成pymol的二进制文件
同软件使用gcc编译ok，可生成二进制文件，但是clang编译报错。

【实际结果】
使用clang编译报错，提示llvm存在bug，返回错误clang-12: error: clang frontend command failed with exit code 139
