Description:
------------
Make install of php-5.2 and php-5.2.1 seems not to work on all our servers running redhat 7.3 (gcc 2.96, kernel 2.4.29). Configure goes well, make seems to work also, but we've got a segmentation fault during make install. 
Everything was OK on these systems with PHP 5.1.6 for instance.

Reproduce code:
---------------
CFLAGS="-O2 -march=i686 -funroll-loops -fomit-frame-pointer -I/usr/include/openssl/" ./configure --prefix=/usr --with-exec-dir=/usr/bin --with-apache=../ --with-config-file-path=/servers/apache/conf --enable-track-vars --disable-debug --enable-safe-mode --enable-inline-optimization --with-gd=/usr/local/gd --with-ttf --with-jpeg --with-jpeg-dir --with-png --with-mm --with-gnu-ld --with-gettext --enable-mbstring --with-curl=/usr/local/curl --with-zlib --enable-bcmath --enable-memory-limit --enable-libxml --with-libxml-dir=/usr/local/libxml2 --with-freetype-dir=/usr/local/freetype --with-mysql=/usr/include/mysql --with-imap --with-kerberos --with-imap-ssl

Actual result:
--------------
make install : 
Installing man pages:             /usr/man/man1/
  page: phpize.1
  page: php-config.1
Installing PEAR environment:      /usr/lib/php/
make[1]: *** [install-pear-installer] Erreur de segmentation
make: *** [install-pear] Erreur 2


The issue seems to be with the sapi/cli/php binary, when "make install" launch this line : 
"/var/tmp/php-5.2.1/sapi/cli/php /var/tmp/php-5.2.1/pear/install-pear-nozlib.phar"
I've got a segmentation fault.

When I run /var/tmp/php-5.1.6/sapi/cli/php /var/tmp/php-5.2.1/pear/install-pear-nozlib.phar" I don't have Segmentation fault. So I think it is because of the php cli.

It would help very much if you build PHP with --enable-debug.

[2007-02-14 13:52 UTC] zesigur at free dot fr

It works changing --disable-debug into --enable-debug !! no more segfault with Your http://snaps.php.net/php5.2-latest.tar.gz

The original php-5.2.1.tar.gz does not work even with --enable-debug.. So there seems to be a problem with this release and --disable-debug, isn't it?

No, --disable-debug is just not that forgiving.
Please provide an account on this machine, I can't see any problems here - everything installs and works just fine.

[2007-02-14 14:26 UTC] zesigur at free dot fr

They are LAN servers with no access from the outside.. But my question is : why does it work with your latest version with --enable-debug and why it does not work with original php-5.2.1? What are the differences between these versions? Is it because of the .phar?

[2007-02-14 14:28 UTC] tony2001@php.net

>But my question is : why does it work with your latest

I said I can't reproduce it.

>What are the differences between these versions?
Run `diff -ru php-5.2.1 php5.2-200702141130` if you want to see the diff.

[2007-02-14 14:34 UTC] zesigur at free dot fr

OK, so I will use this snapshot on these servers, that's OK. Thank you very much for your help !

[2007-02-14 14:42 UTC] tony2001@php.net

Well, I would appreciate if you help us to find the roots of the problem.
First of all, please remove all these custom CFLAGS and see if it works without them.
Then remove --enable-inline-optimization and check it once again.
If that doesn't help, tell me. I'll show you what to do after that.

[2007-02-14 15:25 UTC] zesigur at free dot fr

OK no problem to help you! I've tried with the original php-5.2.1 version. with that :

./configure \
--prefix=/usr \
--with-exec-dir=/usr/bin \
--with-apache=../ \
--with-config-file-path=/servers/apache/conf \
--enable-track-vars \
--enable-safe-mode \
--with-gd=/usr/local/gd \
--with-ttf \
--with-jpeg \
--with-jpeg-dir \
--with-png \
--with-mm \
--with-gnu-ld \
--with-gettext \
--enable-mbstring \
--with-curl=/usr/local/curl \
--with-zlib \
--enable-bcmath \
--enable-memory-limit \
--enable-libxml \
--with-libxml-dir=/usr/local/libxml2 \
--with-freetype-dir=/usr/local/freetype \
--with-mysql=/usr/include/mysql \
--with-imap \
--with-kerberos \
--with-imap-ssl

So, without the CFLAGS, and without --enable-inline-optimization . The problem is the same.
Installing PEAR environment:      /usr/lib/php/
make[1]: *** [install-pear-installer] Erreur de segmentation
make: *** [install-pear] Erreur 2
You can tell me what to try next..

[2007-02-14 15:34 UTC] tony2001@php.net

No, please use the snapshot.

[2007-02-14 16:13 UTC] zesigur at free dot fr

strange...
With the last snapshot :
without CLAGS, enable inline optimization and this : 
./configure \
--prefix=/usr \
--with-exec-dir=/usr/bin \
--with-apache=../ \
--with-config-file-path=/servers/apache/conf \
--enable-track-vars \
--enable-safe-mode \
--with-gd=/usr/local/gd \
--with-ttf \
--with-jpeg \
--with-jpeg-dir \
--with-png \
--with-mm \
--with-gnu-ld \
--with-gettext \
--enable-mbstring \
--with-curl=/usr/local/curl \
--with-zlib \
--enable-bcmath \
--enable-memory-limit \
--enable-libxml \
--with-libxml-dir=/usr/local/libxml2 \
--with-freetype-dir=/usr/local/freetype \
--with-mysql=/usr/include/mysql \
--with-imap \
--with-kerberos \
--with-imap-ssl

It fails with the same error.
If I just add : --enable-debug, it works......

Could you try to run it with valgrind and see if there are any errors?
Try this command:
USE_ZEND_ALLOC=0 valgrind --tool=memcheck ./sapi/cli/php -n -dshort_open_tag=0 -dsafe_mode=0 -dopen_basedir= -derror_reporting=E_ALL -dmemory_limit=-1 -ddetect_unicode=0 pear/install-pear-nozlib.phar -d "/usr/local/lib/php" -b "/usr/local/bin"

You should not see any errors except maybe for some OpenSSL warnings, which we obviously can't fix..

[2007-02-14 16:47 UTC] zesigur at free dot fr

I have some Warnings but no errors :
