Issue 2) Cannot build with --enable-hardening

Using gcc 9.1.0, "configure" step fails because fd passing was
broken, but the real problem was a compilation failure when
"--enable-hardening" is used.  Demonstration:

Issue 3) dovecot/doveconf segfaults on startup

It crashes here while processing dovecot.conf, as does "doveconf"

    (settings-parser.c:1519 in setting_copy())
    *dest_size = *src_size;

It appears *src_size is not an 8-byte address aligned (0x5597c).
It inherits this value from the calling routine as the sum of
"set" (8-byte aligned) + "def->offset"=20 => misaligned address.

32 bit or 64bit? cflags? I use 32 bit cc 12.6 and have no problem. My test with gcc 9.1.0 didn't dump core either.
