Build Identifier:

mserver5: 8347 Segmentation fault ./MonetDB201408/bin/mserver5 -d10 --set mapi_port=49000

after running SQL:
select oid > 0, * from altstartwith;

Reproducible: Always

Steps to Reproduce:

1. Start mserver5 (MonetDB 5 server v11.17.21 "Jan2014-SP3")
2. Start mclient
3. Run SQL commands:
   create table altstartwith (oid oid GENERATED ALWAYS AS IDENTITY, col integer);
   select * from altstartwith;
   select oid > 0, * from altstartwith;

Actual Results:

bash-4.2$ start_mserver5
builtin opt gdk_dbpath = /ufs/dinther/MonetDB201408/var/monetdb5/dbfarm/demo
builtin opt gdk_debug = 0

builtin opt mapi_open = false
