LinuxQuestions.org - PHP-ODBC on OpenBSD 4.1 causes Segmentation fault

I've never setup PHP-ODBC on anything but a Windows box, so I'm not sure if there's a step I missed, but here's what's happening: I'm running OpenBSD 4.1 and trying to use odbc_do() in PHP and it causes a weird error that I can't decipher. Here it is:

Code:

[Mon Jun  4 11:22:55 2007] [notice] Apache/1.3.29 (Unix) PHP/5.1.6 with Suhosin-Patch mod_perl/1.30 mod_ssl/2.8.16 OpenSSL/0.9.7j configured -- resuming normal operations

lazy binding failed!

Any ideas? Did I miss a step? I did the thing to enable the module in php.ini. Here's the [ODBC] chunk in the php.ini file:

Code:

[ODBC]

;odbc.default_db    =  Not yet implemented

;odbc.default_user  =  Not yet implemented

;odbc.default_pw    =  Not yet implemented



; Allow or prevent persistent links.

odbc.allow_persistent = On



; Check that a connection is still valid before reuse.

odbc.check_persistent = On



; Maximum number of persistent links.  -1 means no limit.

odbc.max_persistent = -1



; Maximum number of links (persistent + non-persistent).  -1 means no limit.

odbc.max_links = -1



; Handling of LONG fields.  Returns number of bytes to variables.  0 means

; passthru.

odbc.defaultlrl = 4096



; Handling of binary data.  0 means passthru, 1 return as is, 2 convert to char.

; See the documentation on odbc_binmode and odbc_longreadlen for an explanation

; of uodbc.defaultlrl and uodbc.defaultbinmode

odbc.defaultbinmode = 1
