#47829 [Opn]: Segmentation fault on startup with PDO Firebird compiled in

 ID:               47829
 User updated by:  info at programmiernutte dot net
 Reported By:      info at programmiernutte dot net
 Status:           Open
 Bug Type:         Reproducible crash
 Operating System: Debian Etch x86_64
 PHP Version:      5.3.0RC1
 New Comment:

I did some more experimenting, and I figured that the Crash does not
occur when PDO Firebird is compiled as a shared module and loaded as
extension. PDO Extension seems to work.

Description:
------------
I am getting Segmentation fault on startup, no matter if SAPI apache 2
or CLI. Same Version of PHP and same Firebird Version (2.1.1.) are
running flawlessly on my G4 Mac on Mac OS X 10.4.11, so maybe this is
64bit-related? 
I used gdb to track this down to PDO Firebird Initialisation Startup:

(gdb) run

Failed to read a valid object file image from memory.
