Do you load any extensions in your php.ini ??
(including any zend extensions, like the optimizer)

Description:
------------
Some of our database scripts produce segfaults when they are done. It
is difficult to supply sample code since the segfault depends at least
on the following:
* a successful call to odbc_pconnect('host:node','user', 'pass');
if odbc_pconnect fails there is no segfault
* some (included?) code before odbc_pconnect
While trying to reduce the code i noticed, that include(_once?) is
needed to trigger the problem. That's meant with "some _included_ code"
in the sample below.
* filename
"/var/home/tho/oss/sbwi/bin/php -c /var/home/tho/oss/sbwi/conf -f
/var/home/tho/oss/sbwi/dump1.php"
cores while the similar code in
"/var/home/tho/oss/sbwi/bin/php -c /var/home/tho/oss/sbwi/conf -f
/var/home/tho/oss/sbwi/dump.php"
does not core
The code itself works fine. The segfault always happens after the last
line.
We are connecting to ADABAS using ODBC
configure:
./configure\
--prefix=$(PREFIX)\
--with-adabas=$(adabas_dir)\
--with-openssl=$(PREFIX) \
--disable-session\
--with-db\
--without-gd\
--with-config-file-path=$(PREFIX)/conf
Reproduce code:
---------------
<?
[...some _included_ code...]
$dbhandle = @odbc_pconnect('host:node','user', 'pass');
exit;
?>
Expected result:
----------------
no segfault :-)
Actual result:
--------------
