It might help to tell us which compiler and linker flags you are
already using.

I tried to compile with FPC 3.0.4 for Win32 and it works. The problems
occurs only on FPC 3.0.4 Win64. I edited the function to log to a file some
debug text as first instruction of the function and it's not invoked, so I
think on Win64 Firebird doesn't even make to call the UDF. Anybody could

Yes, this Simple function is just one of a big set of UDFs that we exported
in the same dll/so file. We have been using these functions in production
for more than 10 years. I stumbled upon this issue when I tried to compile
the same working code (without

I use this udfmalloc, on windows is defined as:

Do you check returned value for nil?
BTW, "Integer" is not always right declaration for the argument.

Nothing in the firebird.log
How UDF is declared in DB ?
DECLARE EXTERNAL FUNCTION SIMPLE
CSTRING (254)
RETURNS CSTRING (254) FREE_IT
ENTRY_POINT 'Simple' MODULE_NAME 'SitaUdfLib.dll'
How UDF is declared in Pascal ?

There is no code changes to my UDF source code between the version compiled

Bug in either your UDF or FPC.
