Title: Re: [Firebird-devel] Firebird UDF compiled with Lazarus 2.0.0 and FPC 3.0.4
More than 15 years ago, I found that FPC didn't produce PIC code, and this made UDFs to crash the FB server.
When I was testing, it was really easy to reproduce the problem, specially with SuperServer: ope

I've expected CS but 2.1 or less.
2.5 is already MT product and it always appeared that IsMultiThread in
pascal should match that fact i.e. shold be True. But all that

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?

Two things1. What is calling convention should be cdecl.2. How do you alloc
memory for string?Regards,Karol Bieniaszewski

Ah, I remembered what is wrong with it. FPC by default uses bad single-threaded memory

Yes, but UDF always use cdecl on any platform. Besides, he compiled for x86_64 where
only one calling convention exists. Something else must
I am not familiar with Firebird core dumps, I read this article:
https://www.ibphoenix.com/resources/documents/development/doc_36
I am running Firebird 2.5 Classic configured with systemd [1] . I changed
the .service file to make firebird running as root. I did run the script in
/opt/bin/restoreRo
My guess is that you are using the wrong calling convention for Linux.
Note: IBX uses "stdcall" when accessing the Firebird API under Windows,
but changes to using "cdecl" under Linux.

Check firebird.log for error messages.

Hi,
I compiled a Firebird UDF library written in object pascal. It works
perfectly well on Windows.
