Use var_dump(getcwd());

[root@server php-4.4.1]# ./sapi/cli/php test2.php 
bool(false)
bool(false)
olddir: 
[root@server php-4.4.1]# cat test2.php<?
$olddir = var_dump(getcwd());
var_dump(getcwd());
echo "olddir: $olddir\n";
?>
[root@server php-4.4.1]#

You're doing something wrong, this works just fine for me:

# php -r 'echo getcwd();'
/usr/src/php_5_1

What's the values of HAVE_GETCWD and HAVE_GETWD in main/php_config.h ?

that's why I am reporting that bug, it is working on several servers, but not on this one:

[root@server php-4.4.1]# ./sapi/cli/php -r 'echo getcwd();'
[root@server php-4.4.1]# 

It must be something special on this server, but I don't know where to start to search.
gcc version 3.3.3 
The same problem exists with PHP 4.4.0.

See my previous post.

[root@server php-4.4.1]# grep HAVE_GETCWD main/php_config.h -i
/* #undef HAVE_GETCWD */
[root@server php-4.4.1]# grep HAVE_GETWD main/php_config.h -i
/* #undef HAVE_GETWD */
[root@server php-4.4.1]# 

Is that correct?
That's my configure-string:
'./configure' --with-apxs2 '--host=i386-redhat-linux' '--build=i386-redhat-linux' '--target=i386-redhat-linux-gnu' '--program-prefix=' '--prefix=/usr' '--exec-prefix=/usr' '--bindir=/usr/bin' '--sbindir=/usr/sbin' '--sysconfdir=/etc' '--datadir=/usr/share' '--includedir=/usr/include' '--libdir=/usr/lib' '--libexecdir=/usr/libexec' '--localstatedir=/var' '--sharedstatedir=/usr/com' '--mandir=/usr/share/man' '--infodir=/usr/share/info' '--cache-file=../config.cache' '--with-config-file-path=/etc' '--with-config-file-scan-dir=/etc/php.d' '--enable-force-cgi-redirect' '--disable-debug' '--enable-pic' '--enable-inline-optimization' '--with-bz2' '--with-db4=/usr' '--with-curl' '--with-exec-dir=/usr/bin' '--with-freetype-dir=/usr' '--with-png-dir=/usr' '--with-gd' '--enable-gd-native-ttf' '--with-gdbm' '--with-gettext' '--with-ncurses' '--with-gmp' '--with-iconv' '--with-jpeg-dir=/usr' '--with-openssl' '--with-png' '--with-regex=php' '--with-xml' '--with-expat-dir=/usr' '--with-dom=/usr' '--with-dom-xslt=/usr' '--with-dom-exslt=/usr' '--with-xmlrpc' '--with-pcre-regex=/usr' '--with-zlib' '--with-layout=GNU' '--enable-bcmath' '--enable-exif' '--enable-ftp' '--enable-magic-quotes' '--enable-safe-mode' '--enable-sockets' '--enable-sysvsem' '--enable-sysvshm' '--enable-track-vars' '--enable-trans-sid' '--enable-wddx' '--with-pear=/usr/share/pear' '--with-imap' '--with-imap-ssl' '--with-kerberos' '--with-ldap' '--with-mysql=/usr' '--enable-ucd-snmp-hack' '--with-unixODBC=/usr' '--enable-memory-limit' '--enable-bcmath' '--enable-shmop' '--enable-calendar' '--enable-dbx' '--enable-dio' '--enable-mcal' '--enable-mbstring' '--enable-mbstr-enc-trans' '--enable-mbregex' '--enable-force-cgi-redirect'

Try with just plain `./configure --enable-debug`

it worked.
So I tried different configure-strings, and if I remove '--cache-file=../config.cache' the original configure-string is working.

Thanks!

No bug then.
