Description:
------------
The ibase_trans() function segfaults when you pass connection-id and/or mode to the function.

After comparing both 5.2.x version of interbase.c and 5.3.x version, I found the solution:

# diff interbase.c interbase-fix.c
1128c1128,1129
<       unsigned short i, argn, link_cnt = 0, tpb_len = 0;
---
>       unsigned short i, link_cnt = 0, tpb_len = 0;
>       int argn;

The &argn passed to zend_parse_parameters shall be a pointer to an integer, not to an unsigned short.

Test script:
---------------
$DB = ibase_pconnect($DB_name, $DB_user, $DB_pw );
$TR = ibase_trans($DB);

is enough to trigger the error.

I saw that difference from 5.4 and now i know what was :)
I will merge back patch and 5.3 will look the same like in 5.2 , and 5.4
