I have a WIP patch that adds gcc specific allocator attributes for palloc et
al. Just rebased that. It warns on the new code as follows:
[1489/1804 42 82%] Compiling C object contrib/pgcrypto/pgcrypto.so.p/crypt-sha.c.o
../../../../../home/andres/src/postgresql/contrib/pgcrypto/crypt-sha.c: In function 'px_crypt_shacrypt':
../../../../../home/andres/src/postgresql/contrib/pgcrypto/crypt-sha.c:605:13: warning: pointer 'cp' may be used after

../../../../../home/andres/src/postgresql/contrib/pgcrypto/crypt-sha.c:533:9: note: call to 'pfree' here
533 | pfree(s_bytes);

And it sure seems to have a point. I'm surprised this isn't causing wider
issues...
