Description: OCIDefineByName() causes Apache crash

OCIDefineByName($stmt, "TITLE", &$topic) causes apache to crash.

My table looks like:

CREATE TABLE TESTTABLE
(
        test1 VARCHAR(150) PRIMARY KEY,
        test2 VARCHAR(50),
        test3 VARCHAR(50),
        title VARCHAR(255),
        test4 VARCHAR(255),
        .....
)
TABLESPACE SPACE;

The statement is:
OCIParse($conn, "SELECT test1,test2,test3,TITLE FROM TESTTABLE WHERE TEST1 LIKE 'A%'");

Then I call following OCI methods:
OCIDefineByName($stmt, "TEST1", &$test1);
OCIDefineByName($stmt, "TEST2", &$test2);
OCIDefineByName($stmt, "TEST3", &$test3);
OCIDefineByName($stmt, "TITLE", &$title);

On LAST OciDefineByName apache crashes. This is reproducable. If I comment out last OCI command, the rest of php3 commands are executed successfully.

(I'm running Apache_1.3.4)

TRACKED DOWN LATER:
I've tracked down the problem with the php binary (without apache) and calling the same query again. This is what gdb tells me:

Program received signal SIGSEGV, Segmentation fault.

1112 pval->value.str.val[ pval->value.str.len ] = 0;
