It seems to me like an over-optimization bug by the compiler.

I have fixed the problem by changing the CFLAGS variable from "O3 -mmmx
-march=i686 -mcpu=i686 -funroll-loops" to "-O3 -msse -mmmx -march=i686
-mcpu=pentium4 -mfpmath=sse -funroll-loops". I'm not sure how that
helps, but it's the only thing that fixed it. The second one is the
CFLAGS used by my other RPM build of apache+php.

Yes, I know. But this just means that with valgrind you should be able
to see more.
Run it this way:
USE_ZEND_ALLOC=0 valgrind --tool=memcheck php <script.php>

As I stated earlier, the problem does NOT happen if I enable debug.

Please try to get some more information using valgrind (and
--enable-debug).

The problem actually occurs on several different machines, whenever I
use the RPM built with those configure options. I've tried it on a 2.4
GHz Celeron, a 1 GHz Duron, and a 2.66 GHz P4. Using my alternate RPM
that has the other configure options, I don't see the problem.
That's fortunate, because the one without the problem is the one on all
of my production machines. The problem only happens on my monitoring
machine.
The problem does not happen in CLI, however the configure options are
(yet again) different. I have three different CLI versions, and it
works with all three. Here are their configure options:
'./configure' '--mandir=/usr/share/man'
'--with-config-file-path=/etc/php'
'--with-config-file-scan-dir=/etc/php/cli.d' '--with-mysql=/usr'
'--with-mysqli=/usr/bin/mysql_config' '--with-zlib' '--enable-mbstring'
'--with-openssl' '--disable-cgi' '--enable-pcntl' '--without-pear'
'--enable-soap' '--with-rrdtool' '--with-snmp' '--with-gmp'
'--without-spl' '--without-sqlite' '--without-pdo'
'./configure' '--mandir=/usr/share/man'
'--with-config-file-path=/etc/php'
'--with-config-file-scan-dir=/etc/php/cli.d' '--with-mysql=/usr'
'--with-mysqli=/usr/bin/mysql_config' '--disable-cgi' '--enable-soap'
'--with-readline' '--with-zlib' '--with-ldap' '--with-ncurses'
'--with-imap' '--with-imap-ssl' '--with-kerberos=/usr/kerberos'
'--with-gmp' '--without-spl' '--without-sqlite' '--without-pdo'
'./configure' '--mandir=/usr/share/man'
'--with-config-file-path=/etc/php'
'--with-config-file-scan-dir=/etc/php/gd.d' '--with-mysql=/usr'
'--with-mysqli=/usr/bin/mysql_config' '--with-zlib' '--enable-mbstring'
'--with-openssl' '--disable-cgi' '--enable-pcntl' '--without-pear'
'--enable-soap' '--with-gd' '--enable-gd-native-ttf'
