Description:
------------
When doing a 'make install', the result is :
Installing PHP SAPI module:       apache
[activating module `php5' in /usr/local/apache/conf/httpd.conf]
cp libs/libphp5.so /usr/local/apache/libexec/libphp5.so
chmod 755 /usr/local/apache/libexec/libphp5.so
cp /usr/local/apache/conf/httpd.conf /usr/local/apache/conf/httpd.conf.bak
cp /usr/local/apache/conf/httpd.conf.new /usr/local/apache/conf/httpd.conf
rm /usr/local/apache/conf/httpd.conf.new
Installing PHP CLI binary:        /usr/local/bin/
Installing PHP CLI man page:      /usr/local/man/man1/
Installing PEAR environment:      /usr/local/lib/php/
make[1]: *** [install-pear-installer] Segmentation fault (core dumped)
make: *** [install-pear] Error 2



When running sapi/cli/php the same result occurs.

Can you try with --enable-debug and give the  
configure-line with as few parameters as possible, or was  
this already just ./configure?

[2005-08-26 21:44 UTC] wim at godden dot net

Just ./configure works fine.

It seems once --with-openssl is added, the problem occurs.
Running OpenSSL 0.9.8, compiled from scratch using option 'shared' (no package install possible).

[2005-08-28 01:00 UTC] sniper@php.net

What is the full configure line you used?

[2005-08-28 20:06 UTC] wim at godden dot net

./configure --with-apxs=/usr/local/apache/bin/apxs --with-openssl=/usr/local/ssl --with-xmlrpc

(--with-xmlrpc required for PEAR, when using --without-pear the error ofcourse doesn't occur).

[2005-08-28 23:43 UTC] sniper@php.net

I can not reproduce this. What libxml2 versin do you have installed?

[2005-08-29 13:46 UTC] wim at godden dot net

libxml2.6.19 being used, compiled with no parameters.

I see this during configure :
checking whether to enable LIBXML support... yes
checking libxml2 install dir... no
checking for xml2-config path... /usr/local/bin/xml2-config
checking whether libxml build works... yes
checking for OpenSSL support... yes
...
checking for OpenSSL version... >= 0.9.6
...
checking for xml2-config path... (cached) /usr/local/bin/xml2-config
checking whether libxml build works... (cached) yes
checking for XMLReader support... no
checking for XMLRPC-EPI support... yes
checking libexpat dir for XMLRPC-EPI... no
checking iconv dir for XMLRPC-EPI... no
checking for xml2-config path... (cached) /usr/local/bin/xml2-config
checking whether libxml build works... (cached) yes

[2005-08-29 13:55 UTC] sniper@php.net

Try compile with --enable-debug and run the make line in question under gdb:

# gdb sapi/cli/php
(gdb) run -n -dshort_open_tag=0 -dsafe_mode=0 \
 pear/install-pear.php -d /tmp/test/  \
 -b /tmp/test/bin/ pear/package-*.xml

[2005-08-29 14:04 UTC] wim at godden dot net

[2005-08-29 14:07 UTC] sniper@php.net

Can you provide the rest of that backtrace..?

[2005-08-29 14:08 UTC] wim at godden dot net

That's all being shown.

[2005-08-29 14:09 UTC] sniper@php.net

(gdb) bt

[2005-08-29 14:15 UTC] wim at godden dot net

I knew bt... but this is all bt gives :
#0  0x08321869 in CRYPTO_get_ex_new_index ()

[2005-08-29 16:50 UTC] sniper@php.net

Apparently there's something very wrong within your system. I'm unable to reproduce this and nobody else has reported this so it's not PHP bug (yet).

[2005-08-29 17:48 UTC] wim at godden dot net

Any suggestions on how to try to find a solution to this ?
