Got a problem with Exim 3.22 here, built from a freshly cvsup'ed ports
collection. All attempts at starting it are met with:
Segmentation fault.
Apr 30 09:01:47 lists /kernel: pid 86382 (exim), uid 0: exited on signal 11
This is with simple configure files that work on other boxes running
4.2-STABLE and Exim 3.20.
I commented out the lines that build X in the port Makefile:
# If WITHOUT_X11 is not defined, the eximon monitor, which requires X, will
# be built. Comment it out unless you have or want XFree86 installed!
#.if !defined(WITHOUT_X11)
#USE_XLIB= yes
#.endif
No compiler opts, and Exim built without errors.
One difference is that the segfaulting version of Exim is linked against the
re-entrant version of libc:
# ldd /usr/local/sbin/exim
/usr/local/sbin/exim:
libcrypt.so.2 => /usr/lib/libcrypt.so.2 (0x280d9000)
libwrap.so.3 => /usr/lib/libwrap.so.3 (0x280ee000)
libperl.so.3 => /usr/lib/libperl.so.3 (0x280f6000)
libm.so.2 => /usr/lib/libm.so.2 (0x28194000)
libc.so.4 => /usr/lib/libc.so.4 (0x281b0000)
libc_r.so.4 => /usr/lib/libc_r.so.4 (0x28248000)
libutil.so.3 => /usr/lib/libutil.so.3 (0x282fe000)
... whereas the working ones aren't.
I ran ktrace/kdump, and this is what it shows towards the end when the
program segfaults:

Have asked about this on the Exim list as well... any help would be most
welcome.
