Hi, using FB 2.5.1 on Debian stable (FB is from unstable, tried also
with FB 2.5.0 from stable with the same results).

Example taken from
http://www.firebirdsql.org/file/documentation/reference_manuals/reference_material/html/langrefupd25-bigint.html

In a newly created database, using isql connected as SYSDBA:

SQL> create table WholeLottaRecords (
CON> id bigint not null primary key,
CON> description varchar(32)
CON> );
Statement failed, SQLSTATE = 42000
unsuccessful metadata update
-cannot create index RDB$PRIMARY27
SQL>

Why does it fail?

Thanks...
EB
