Description

TEST_CASE_CLASS works with version 2.4.7, not with v2.4.8. It is broken by commit 95a7853.

Steps to reproduce

TEST_CASE_CLASS is not documented nor tested by the CI. However if I take this example proposed in the description of the feature, and simplify it :

#include "doctest/doctest.h"

class my_type {
    int data = 5;

    TEST_CASE_CLASS("all_to_all_v 2") {
        my_type local;
        CHECK(local.data == 2);
    }
};

This does not compile. GCC error message:

doctest.h:1980:64: error: 'DOCTEST_ANON_VAR_4' was not declared in this scope; did you mean 'DOCTEST_ANON_VAR_0'?
1980 |     global_prefix DOCTEST_GLOBAL_NO_WARNINGS(DOCTEST_ANONYMOUS(DOCTEST_ANON_VAR_), 

Extra information

Note that a (better?) alternative to TEST_CASE_CLASS is mentioned here. Maybe we should try to implement the more flexible feature rather than fixing this one.

On a personal note, I was just trying to check if TEST_CASE_CLASS could solve my problem (a bug in MPI_TEST_CASE with several SUBCASE). But it will not (even when fixed). So I personally don't need the fix.
