Possible glitch in php-4.0.1pl2 ?

Maybe I've found a glitch. 1) On my system neither 4.0.1 nor 4.0.1pl2 seemed to work (while 4.0.0 is perfect): Apache died before it could write a single line to the log file. I have compiled v4.0.1pl2 on three different systems (a dual PII, a K6 and a K7), all running RedHat 6.1 but with different kernel versions (2.2.16+reiserfs, 2.2.14+reiserfs). Apache is 1.3.12 patched with apache-1.3.12+ssl-1.39 (I've tried also with apache-1.3.12+ssl-1.40), openssl is 0.9.5a and these additional DSO modules: - mod_perl 1.24 (tried with this module unloaded, also) - mod_bandwidth (tried with this module unloaded, also) - mod_put (tried with this module unloaded, also) - php 3.0.16 (tried with this module unloaded, also) Apache was configured this way: ./configure \ --prefix=/usr \ --with-layout=RedHat \ --enable-module=all \ --enable-shared=max \ --disable-rule=WANTHSREGEX \ --disable-module=auth_dbm \ --with-perl=/usr/bin/perl \ --enable-suexec \ --suexec-docroot=/home/httpd/html \ --suexec-caller=nobody \ --add-module=mod_bandwidth.c \ --add-module=mod_put.c PHP 4 was configured this way: ./configure \ --with-mysql=/usr \ --with-zlib \ --with-xml \ --with-gd \ --with-config-file-path=/etc/httpd/conf \ --enable-versioning \ --with-apxs=/usr/sbin/apxs \ --enable-memory-limit \ --enable-track-vars \ --enable-trans-sid 2) On a fourth machine (an old Am5x86 133MHz with 32Mb RAM, RedHat Linux 6.1, kernel 2.2.16+reiserfs, openssl 0.9.4) with the same Apache/PHP configuration, Apache started, but I got a segmentation fault each time a gz function was called. 3) I read a post by Antoine Pouch who noticed that "commenting out the directives loading PHP4 module (LoadModule & AddModule) from httpd.conf, apache starts fine. And if i uncomment the PHP directives and send a SIGHUP to apache, it restarts fine with PHP module loaded !!" 4) For me it was the same, and once again calling a gz function resulted in a segmentation fault. 5) I've compiled php-4.0.1pl2 without zlib support and dso got loaded and executed as it should... 6) I've made a diff between /usr/src/php-4.0.0/ext/zlib/php_zlib.h and /usr/src/php-4.0.1pl2/ext/zlib/php_zlib.h I found that in the latter there were two more declarations for gzcompress and gzuncompress, but also some missing conditional defines: #if COMPILE_DL #undef HAVE_ZLIB #define HAVE_ZLIB 1 #endif at line 31. With these lines added, now I have a *working* php-4.0.1pl2 dso. 8) Can anyone confirm wether this is a bug or not?
