--- Comment #8 from Richard Biener <rguenth at gcc dot gnu.org> ---
It compiles successfully for me with the FSF 7.3.0 release and -O0 -fPIC
-fdollars-in-identifiers - it does use a lot of memory though (~6GB).
Note that GCC 7 is no longer supported.
With GCC 10.2 I see

Confirmed as memory/compile-time hog.
