When I run "select * from var();" in a freshly started database, I get an immediate assertion failure:

2015-04-19 05:05:51 ERR gt[6067]: mserver5: ../../../../MonetDB-11.19.7/sql/backends/monet5/sql.c:1378: sql_variables: Assertion `v->vtype == 5' failed.

v->vtype is 4 (TYPE_bat) in this case; I guess this is because the sql_variables MAL op is declared to return a bat in the sql.mal, but the argument checking wants a pointer to int.

The issue can not be reproduced on the default branch.
I consider it closed until further notice.

For the records:

The problem is reproducible as reported with Oct2014 and Oct2014-SP1,
but appears to be fixed as of Oct2014-SP2.

Please upgrade to the latest Oct2014-SP3 (or the upcoming Oct2014-SP4 once it will be released).
