Description:
------------
I'm using interbase 7. 

I made a table using a BOOLEAN field. Everything worked fine, until I tried to extract data from the table. Then I found out that the BOOLEAN field was crashing PHP (and, in succession, apache). 

The error I got with PHP was (command line client): 
"Warning: ibase_fetch_assoc(): Dynamic SQL Error SQL error code = -804 Incorrect values within SQLDA structure  in [...]"

(for search-sake: the Apache error was "Parent: child process exited with status 3221225477 -- Restarting.")

The problem is not a database failure; IBconsole and Database Workbench both handle the test-SQL perfectly.

Reproduce code:
---------------
I left the PHP code out, for readability. I'm using ibase_connect(), ibase_query() and ibase_fetch_assoc().
Run the following SQL first:
CREATE TABLE TEST
(
  ID                     INTEGER         NOT NULL,
  PUBLISHED              BOOLEAN         DEFAULT 0,
 CONSTRAINT PK_CMS PRIMARY KEY (ID)
)
;

Fill the database with some lines, it doesn't matter what exactly:
INSERT INTO TEST(ID, PUBLISHED) VALUES(1,false);
INSERT INTO TEST(ID, PUBLISHED) VALUES(2,true);
INSERT INTO TEST(ID, PUBLISHED) VALUES(3,false);
INSERT INTO TEST(ID, PUBLISHED) VALUES(4,true);

Then try to extract data from the database:
SELECT * FROM TEST;

Expected result:
----------------
(after ibase_query()): 

an array with the values from the database.


Actual result:
--------------
A big fat error, where after PHP and Apache will crash. The problem occurs on the line with ibase_query().
