 Spoiler: This has the same root cause as ticket#31590.  I'm only
 submitting this in case others run into clang-introduced segmentation
 faults running their own php code rather than just when installing php-
 related ports.

 On a 64 bit lion machine
 {{{
 tracy-pc:~ dwilks$ uname -a
 Darwin tracy-pc.win.intacct.com, intacct.com 11.2.0 Darwin Kernel Version
 11.2.0: Tue Aug  9 20:54:00 PDT 2011; root:xnu-1699.24.8~1/RELEASE_X86_64
 x86_64
 }}}

 In a reasonably fresh, clean, macports tree
 {{{
 tracy-pc:~ dwilks$ sudo port uninstall inactive
 tracy-pc:~ dwilks$ sudo port -fp uninstall --follow-dependents installed
 tracy-pc:~ dwilks$ sudo port clean all
 }}}

 With XCode 4.2 installed

 With MacPorts configured to generate 32 bit binaries (not sure if this
 matters)
 {{{
 tracy-pc:~ dwilks$ grep build_arch /opt/local/etc/macports/macports.conf
 build_arch                      i386
 }}}

 Install php 5.3.9 (happened with the previous 5.3.8 too)
 {{{

 or
 /opt/local/etc/php5/php.ini-production (if this is a production server).
 }}}

 Create a simple php script that calls array_intersect
 {{{

 <?php
 $arr1 = array('a', 'b');
 $arr2 = array('c', 'd');
 echo "about to call array_intersect\n";
 if (array_intersect($arr1, $arr2)) {
     echo "Yes\n";
 } else {
     echo "No\n";
 }
 echo "all done\n";
 }}}

 And execute it
 {{{
 tracy-pc:~ dwilks$ /opt/local/bin/php -n -f ~/test.php
 about to call array_intersect
 Segmentation fault: 11
 tracy-pc:~ dwilks$
 }}}

 Re-install php5 using llvm-gcc-4.2
 {{{

 tracy-pc:~ dwilks$ sudo port uninstall php5

 or
 /opt/local/etc/php5/php.ini-production (if this is a production server).
 }}}

 And then run the same test
 {{{
 tracy-pc:~ dwilks$ /opt/local/bin/php -n -f ~/test.php
 about to call array_intersect
 No
 all done
 }}}

 As a side note downloading php 5.3.9 and building from source worked
 perfectly since it uses gcc which points to llvm-gcc-4.2.
