FYI: I also see this on FreeBSD via the lang/gcc12 port (that,
in my installed context, is at 12.2.0), using the default library:
libstdc++ .

I do not see any failure on FreeBSD when I use -stdlib=3Dlibc++ on the two
command lines:

# g++12 -std=3Dc++20 -stdlib=3Dlibc++ -pedantic -Wall -Wextra -fmodules-ts =
-fPIC
-xc++-system-header memory
# g++12 -std=3Dc++20 -stdlib=3Dlibc++ -pedantic -Wall -Wextra -fmodules-ts =
-fPIC
-omodule_shared_ptr_failure module_shared_ptr_failure.cpp
