The GNU equivalent is -D_GLIBCXX_ASSERTIONS: https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_macros...

It mostly impacts templated code, so it's a compiler flag, not a linker flag. Many distributions have been using this flag to build C++ code for quite some time.

(And this concerns GNU libstdc++, not glibc, so different licensing rules apply.)

A considerable number of C++ libraries are header-only, so having this macro defined is the onus of the libraries' consumers, rather than just the package managers'.

Also, I mentioned no libc equivalent, and that remains true. Regardless of the libc distribution (glibc, musl, BSD, macOS libSystem), none of them have a debug mode in the vein that Windows UCRT does.
