I am wondering when we can drop support for g++-8. All supported operating systems, except for CentOS Stream 8 offer a greater version:

* Ubuntu Focal: gcc 9 (https://packages.ubuntu.com/focal/gcc)
* Debian Bullseye: gcc 10 (https://packages.debian.org/bullseye/gcc)
* CentOS 8 Stream: gcc 8, with EOL of " May 31st, 2024 " (https://www.centos.org/centos-stream/)

The rationale for dropping it would be that there are currently occasional compile failures with perfectly valid C++-17 code, for example:

* `error: call to non-‘constexpr’ function ‘void __assert_fail(const char*, const char*, unsigned int, const char*)’ assert(false);` (https://godbolt.org/z/bxaMnfcsa)
} else {
                return rec->label;
            }
        case Address:
            return rec->address;
        } 
        assert(false);
    } else if (role == Qt::FontRole) {
        switch (column) {
        case Label:
            return QFont();
        case Address:
            return GUIUtil::fixedPitchFont();
        } 
        assert(false);
    } else if (role == TypeRole) {
        switch(rec->type)
        {
        case AddressTableEntry::Sending:
            return Send;
        case AddressTableEntry::Receiving:
            return Receive;
        case AddressTableEntry::Hidden:
            return {};
        } 
        assert(false);
    }
    return QVariant();
}
