So the database server crashes, not web server, right?

Description:
------------
Using the php_interbase.dll extension causes Firebird instability
(Crashes, Deadlocks, and BUGCHECKs).
I tried Firebird 1.5.2, Firbeird 1.5.3 and Firebird 2.0 RC1
I tried PHP 5.1.2, PHP 5.0.5
It happens most often while PHP is running as an Apache2 module. It
happens less often, but still happens, when
PHP is running as a CGI under Apache2
I believe it is a thread-safety issue in the
php_interbase.dll or in the gds32.dll that comes with PHP.
I tried using the GDS32.dll from Firebird, and it has similar
problems.
I know that this is a problem either with php_interbase.dll
or with gds32.dll because when I use ODBC to connect to
firebird everything works great.
Reproduce code:
---------------
The database has to be under heavy load to reproduce this.
I have 50-200 simultaneous connections to the database with
a combination of read-only and write transactions and a lot
data going back and forth.
Expected result:
----------------
I expect the native access method to firebird to be stable.
Actual result:
--------------
I get BUGCHEKs, CRASHES, and unexplained DEADLOCKS.
FB2.0 RC1:
