Description:
------------
I'm trying to run the latest snapshot, php5-200509011630, on i686 machine running debian sarge, apache2 sapi.

It compiles without any problem, but 'make install' fails with the following:
Installing PEAR environment:      /usr/local/php5/share/pear/
make[1]: *** [install-pear-installer] Error 1
make: *** [install-pear] Error 2

It seems like the CLI bin and the apache2 module were installed, but when running php -v, the program just exists (no crash):
root@damka:~# /usr/local/php5/bin/php -v
root@damka:~#

GDB output:
(gdb) run
Starting program: /usr/local/php5/bin/php
[Thread debugging using libthread_db enabled]
[New Thread 1076854912 (LWP 1377)]

Program exited with code 01.
(gdb)

When running as apache2 module, it crashes immediately when getting the first PHP request. Backtrace:

Program received signal SIGSEGV, Segmentation fault.

PHP was configured with the following parameters:
./configure \
        --prefix=/usr/local/php5 \
        --with-apxs2=/usr/bin/apxs2 \
        --with-zlib \
        --with-mysql=shared \
        --with-pgsql=shared \
        --with-sqlite=shared \
        --with-pdo=shared \
        --with-pdo-pgsql=shared \
        --with-pdo-mysql=shared \
        --with-pdo-sqlite=shared \
        --with-pear=/usr/local/php5/share/pear \
        --with-xmlrpc \
        --enable-soap \
        --with-gettext=shared \

        --with-jpeg-dir=shared,/usr \
        --with-xsl=shared \
        --enable-memory-limit

php-5.1.0RC1 works without any problems with the very same configuration on the same machine.
