PROBLEM:

I have a page which accepts user input and a page which processes that input.  The input goes into fields of an associative array.  Next, the ldap_modify (or ldap_add) function is called:

ldap_modify ($connection, $dn, $inputArray)

PHP crashes immediately.  This bug is new to PHP4 because the same code performed fine under PHP3.

WORKAROUND:

I have found that if I append a zero-length string to each field of the array, the LDAP functions work perfectly.  For instance:

$inputArray[department] = $txtDepartment . "";

SUPPORTING INFORMATION:

I am running Open LDAP, slapd version:

slapd 1.2.7-Release (Mon Sep 20 22:37:14 CDT 1999)

Here is a backtrace:

Program received signal SIGSEGV, Segmentation fault.

Please try latest CVS. This should be fixed there.
