I'm using str_replace to fill out mailing label templates with data from a database. When I came up with a record with empty string fields I got a seqfault. I've tracked the problem down to str_replace -- simplified in the following script. If you insert a space in $replaceArray['NAME'] or add a space at the end of $lines[0] after {name} it won't segfault. Note that the ADDRESS field has the same layout, but doesn't cause a segfault, however if I reduce the arrays to *just* the NAME fields, then it doesn't segfault either. Weirdness.

<?php
$searchArray = array (
    "NAME" => "{name}",
    "ADDRESS" => "{address}" );
$replaceArray = array (
    "NAME" => "",
    "ADDRESS" => "" );
$lines = array(
    "{name}",
    "{address}",
    "",
    ""
    );
$newlines = str_replace($searchArray, $replaceArray, $lines);

print_r($lines);
print("<br>\n");
print_r($newlines);
print("<br>\n");
?>

On MacOSX I used this configuration:
	--with-xml \
	--with-zlib \
	--with-apxs=/usr/sbin/apxs \
	--with-openssl \
	--enable-trans-sid \
	--with-pdflib=/Users/steve/build/pdflib/pdflib-4.0.1/bind/c \ 	--enable-shared=pdflib \
	--with-mysql=/usr/local

On Linux PPC (2.2.18) I used this configuration:
       --with-xml \
        --with-zlib \
        --with-apxs=/usr/sbin/apxs \
        --with-openssl \
        --enable-trans-sid \
        --with-pdflib=/usr/local \
        --enable-shared=pdflib \
        --with-mysql=/usr \
        --enable-openbase_module
