Our server is Red Hat Enterprise Linux Server release 6.10 (Santiago), GCC version g++ (GCC) 4.4.7 20120313 (Red Hat 4.4.7-23). I knew this is probably caused by the very ancient GCC version, however we can't really ask to update the server easily. If sass can support the older version of GCC with different switches, that will be very helpful.

Thanks!

I encounter this same error when I try to install sass from GitHub on macOS 11.3.

I also encounter this error when installing on macOS 12.0.1.
