macOS Monterey下引入<cmath>编译报错:未找到numeric_limits模板

编译仅含#include <cmath>的C++程序报错的解决方案求助

运行仅包含一行#include <cmath>的C++程序时编译失败,报错信息如下:

% g++ cmath-bug.cpp
In file included from cmath-bug.cpp:1:
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/v1/cmath:642:26: error: no template named 'numeric_limits'
    bool _FloatBigger = (numeric_limits<_FloatT>::digits > numeric_limits<_IntT>::digits),
                         ^

......

  } else if (__r <= _Lim::lowest()) {

    return _Lim::min();
           ^

已查找相关讨论帖子但问题仍未解决,系统及环境信息如下:

% xcode-select -p 
/Library/Developer/CommandLineTools

% g++ -Wp,-v -E -

End of search list.

恳请各位提供解决方案或建议!
