I discovered this completely by randomly removing various CFLAGS and LDFLAGS.

Created attachment 465446 [details] Output of 'strace -f rpcbind -df'
I can confirm this issue on hardened ~amd64, rebuilding without --as-needed fixed it for me. This is a weird one to debug (or my systemd-foo is not yet up to par since I had to stare at it for quite some time).
Looks hardened-specific.
FWIW, I no longer run a hardened system (rebuilt the system due to the whole grsecurity fiasco), so this no longer affects me.
This version is long gone. Reopen if still applicable.
