请问如何在blade中应用AddressSanitizer

[kaocs]

如题

[WindLeeWT]

修改 BLADE_ROOT 如下

cc_config(
    cppflags = [
        # Other flags...
        '-fsanitize=address',        
    ],
    # Other configurations...
    linkflags = [
        # Other flags...
        '-fsanitize=address -static-libasan', 
    ]
)

此外，需要注意的是，使用 AddressSanitizer 时，不能链接其他的内存管理库，例如 tcmalloc/jemalloc

考虑支持命令行启用

[paleyl]

blade启动前，先执行下面命令，不知是否可行 export CPP="cpp -fsanitize=address" export CXX="c++ -fsanitize=address" export CC="gcc -fsanitize=address" export LD="c++ -fsanitize=address"

cc_config(
    cppflags = [
        # Other flags...
        '-fsanitize=address',        
    ],
    # Other configurations...
    linkflags = [
        # Other flags...
        '-fsanitize=address -static-libasan', 
    ]
)

请问这个'-fsanitize=address -static-libasan', 对gcc的版本有要求吗？ Linking Shared Library build64_release/app/brand/common/libdatetime.so g++: error: unrecognized command line option '-fsanitize=address -static-libasan'

分开写呢？分别用引号包括，逗号分割
