hello,

please read the whole thread - i have included the script AND i have also tried it 
with the latest development snapshot. i really have included all i have :)
for me it looks like a bug in the echo function (vfprintf.c). the script doesn't crash 
without the echo funtions. it also crashes with "print".

regards

daniel

What was the script used to generate that backtrace?
Also, could you try and check if this happens with
latest CVS snapshot: http://snaps.php.net/

here is the core dump (i managed it with the cgi version):
so the error isn't anymore apache related i guess - i'll move the type...

/*note: this error comes while loading the symbols --- 

(before i started the actual backtrace
*/

hello,

i am using apache 1.3.20 with php-4.0.6
since my update to the 1.3.20 i have strange segmentation faults when i access some 
scripts.
error_log:
[notice] child pid 9707 exit signal Segmentation fault (11)

PLEASE NOTICE:
i have also tryed it with the latest development snapshot - the same

here is my configuration: 
'./configure' '--prefix=/usr' '--with-config-file-path=/etc' '--enable-debug' 
'--with-apxs' '--disable-debug' '--enable-discard-path' '--with-exec-dir=/usr/bin' 
'--with-regex=system' '--with-gettext' '--with-gd=shared' '--with-jpeg-dir=/usr' 
'--with-png' '--with-zlib' '--with-db2' '--with-db3' '--with-gdbm' 
'--enable-magic-quotes' '--enable-safe-mode' '--enable-sysvsem' '--enable-sysvshm' 
'--enable-track-vars' '--enable-yp' '--enable-ftp' '--with-mysql=/usr' 
'--without-oracle' '--without-oci8' '--with-recode' '--with-xml'

i have allready tryed to disable things like xml or regex or recode - the same...

here is a short demo script to reproduce the error:

<?
$ar = array("hund","katze","schwein","kuh","kamel");

function ar1($ar)
{
        reset($ar);
        foreach($ar as $key => $val)
        {
                if($val != "kuh")
                {
                        echo "f1 $key => $val<br>";
                }
                else
                {
                        ar2($ar);
                }
        }
}

function ar2($ar)
{
        foreach($ar as $key=>$val)
        {       
                if($val=="kuh")
                {
                        echo "f2 $key => $val<br>";
                }
                else
                {
                        ar1($ar);
                }
        } 
}

ar1($ar);
?>

infortunately apache refuses to produce a core dump in this case

please help
daniel
