Finally I got it working. You were right Tom Lane. I actually did not copy the corrected source file onto the server
andthus still had this "mysterious" failure. So, palloc0 is the solution. Thanks again.

Gregor Trefs

Well, yes. I wrote a little make file which takes care of this part (except restarting the session):
INCLUDEDIRS += -I$(shell pg_config --includedir-server) LIBDIR = -L$(shell pg_config --libdir) LIBINSTALL = $(shell
pg_config--pkglibdir)
integrated_c.so: integrated_c.c Makefile
gcc -fpic -o integrated_c.o -c integrated_c.c $(INCLUDEDIRS)
gcc -shared -o integrated_c.so integrated_c.o $(LIBDIR) -lmpfr -lgmp
cp integrated_c.so $(LIBINSTALL)

Mph ... you're aware that you have to start a fresh session to load a new version of a .so into the backend?
