Operating System: fc3
PHP Version: 4.3.11
New Comment:
Ok, it seems that the bug was somewhere else, in the portal I use
(tikiwiki).
It's true that it didn't crash if I put a return just before the
assignment, and that it did otherwise, but the crash was really
somewhere else, due to "infinite" recursion (limited to 64 by php). I
corrected the bug in tikiwiki.
Thanks to all people who checked this, and sorry for the
inconvenience.
Regards,
Yannick Majoros

You can even forget about the foreach loop, and thus var: same problem
if I remove them...

$val is some value extracted from a database. The foreach loop goes
through every column of the data extracted from the current row ($res).
Here are the values contained in $res when the crash occurs (on 5th
iteration in 'while'):
"mvanhXXX","Marie-Anne Van HXXX",1,1,1,1,0
I had to replace some name with XXX for privacy, but it doesn't contain
any special character. BTW, the same happens if i just leave the iconv.
If I replace the "bad" line with this:
$wikireq[$id][]='';
The crash doesn't occur (but I don't get my data).

What is the value of $val variable.

Description:
------------
PHP is crashing on some page (segfault), at least on two servers. It
crashes when I try to create a new array element (see code), not
always, but always in the same conditions.
Same with 4.3.10, 4.3.11 and latest cvs.
configure:
'./configure' '--with-apxs2' '--with-iconv'
Reproduce code:
---------------
while ($res=$result->fetchRow(DB_FETCHMODE_ASSOC))
{
// TODO: make iconv optional
foreach ($res as $key=>$val)
$res[$key]=iconv("ISO-8859-1","UTF-8",$val);
////// CRASHING ON FOLLOWING LINE AFTER 5 ITERATIONS (DATA DEPENDANT)
$wikireq[$id][]=$res;
}
Expected result:
----------------
should not crash!
Actual result:
--------------
crash boom, this line in apache error.log:
[Tue May 03 19:33:21 2005] [notice] child pid 10313 exit signal
Segmentation fault (11)
