works properly on Windows and Linux when compiled with
FPC 2.6.4 (Lazarus 1.2.6)
Does anybody have any clue what could cause this issue on Windows?

How memory for return parameter is allocated ?
I use this udfmalloc, on windows is defined as:
function udfmalloc(Size: Integer): Pointer; cdecl; external 'ib_util.dll'
name 'ib_util_malloc';

Hi,
I compiled a Firebird UDF library written in object pascal. It works
perfectly well on Windows.
On Linux I get this error:
SQL> select SIMPLE('test') from client;
Statement failed, SQLSTATE = 08006
Error reading data from the connection.
Firebird Version: Classic 2.5.9.27139-0
Lazarus Versi
gt; but changes to using "cdecl" under Linux.

Thank you all guys, I finally managed to fix the issue:
- There was an initialization section in one unit imported that
set IsMultiThread = True
- I removed the cthreads unit in the uses clause.
Does anybody have any clue what are the implications of these changes?
