I have some selfmade UDF's that is working fine on a Windows server (XP,
FB1.5 RC4-RC9).
The UDF's is written in Delphi(on Windows) and Kylix(on Linux).
As soon as i move the database to Linux (RedHat 9.x, FB 1.5 CC RC8), the
server dies instantly (connection is broken)when calling the UDF. No entry
in
Firebird.log. The same thing happens either the call is coming from my
application or from ISQL. HOWEVER If I connect thru IBexpert, and run the
SQL from
the SQL Editor it works fine!!.
What is going on ? I have no real experience with UDF's and Linux, so this
might be trivial, but I really need some help on this.

The UDF's are typically decleared like this:

function kidfromint(var V1, prefix,lengde : integer) : PAnsichar; cdecl;
export;
...


function kidfromstr(V1 : PAnsichar ; var prefix,lengde : integer) :
PAnsichar; cdecl; export;
...


DECLARE EXTERNAL FUNCTION KIDFROMINT
INTEGER,
INTEGER,
INTEGER
RETURNS CSTRING(25)
ENTRY_POINT 'kidfromint' MODULE_NAME 'flexisoftudf'

DECLARE EXTERNAL FUNCTION KIDFROMSTR
CSTRING(25),
INTEGER,
INTEGER
RETURNS CSTRING(25)
ENTRY_POINT 'kidfromstr' MODULE_NAME 'flexisoftudf'
