Description:
------------
Im using FreeBSD 8.0 the result on 7.x is the same
My Firebird client version is 2.0.3 server have Yaffil (Firebird 1.5
modification)
Trying to connect using
ibase_connect($database,$user,$pass,'WIN1251','100','3')
make a segmentation fault into apache 2.2.14 log
script produce nothing
Trying to use PDO
$conn = new PDO("firebird:dbname=".$database,$user,$pass);
this produce the same trash
Some time ago a have an earlier version on PHP and Firebird client
1.5.3 and have no problem. But it is not a firebird problem because my C
program that communicates with firebird have no problem.
Trying to resolv it, I try to fix it myself editing
ext/interbase/interbase.c
First i comment isc_attach_db function, and the is no more faults.
The next i rewrite the _php_ibase_attach_db function the same way that
I use in my C code, but i change nothing. Possible Error is in the data
manipulation after connection because structures changed to version
2.0/2.1
PS. Maybe I need to repost it as and PDO bug also ?
Reproduce code:
---------------
ibase_connect($database,$user,$pass,'WIN1251','100','3')
$conn = new PDO("firebird:dbname=".$database,$user,$pass);
Actual result:
--------------
segmentation fault in apache 2.2.14 log
