rfunc and memory leak

hi,

my problem is the same that has been discussed here here

I've a Firebird DB server (1.5.2) under RHE. I've compiled the rfunc UDF library using the default makefile.linux. With this UDF the server has a memory leak and the memory grows 'ad infinitum' (500 MB after 2 days, 16Kb on every connection).

As suggested here, i've compiled the UDF without linking at fbclient.so (without -l$(GDS_NAME)) and NO memory leak occurs anymore (of course i'm not able to use function that use TIMESTAMP, ....)

The error is reproducible on two different machines (Mandrake e RHE).

Any suggestions?

PS: Is it possible that nobody has this problem?

Thanx.

Ciao.
Leonardo
