Trying to fetch http://freedns.sgh.waw.pl/ I get crash, while http://freedns.sgh.waw.pl/index.php everything works as expected. Of course the first one should work exactly as the latter. (And it did until I recompiled PHP.)

HTTP daemon is Apache 1.3.27
DirectoryIndex contains index.php
PHP is run as CGI via AddHandler cgi-script
This "freedns.sgh.waw.pl" is (namebased) VirtualHost with DocumentRoot in user directory

Any script would do, simple echo "hello".

(gdb) bt
#0  0xef125448 in strlen () from /usr/lib/libc.so.1
#1  0x12823c in _estrdup (s=0x0)
    at /services/apache/src/php-4.3.2RC2/Zend/zend_alloc.c:363
#2  0x150a5c in init_request_info ()
    at /services/apache/src/php-4.3.2RC2/sapi/cgi/cgi_main.c:709
#3  0x1510d0 in main (argc=2, argv=0xeffffac4)
    at /services/apache/src/php-4.3.2RC2/sapi/cgi/cgi_main.c:1238

(gdb) fr 2
(gdb) p script_path_translated
$6 = 0x0

Adding "cgi.fix_pathinfo = false" to php.ini fixed things.
