6.4 beta crashed backend

I don't know if this is the correct place to post
this message or if the bug in question has already
been fixed but the following query crashed the
backend. Note however, that when there is only one
constant in the IN () list, the query works:

flock error for /tmp/.s.PGSQL.5432

Again, if the same query is issued, but there is only
once constact in the IN () list, i.e.:

SELECT employees.lastname, employees.firstname, employees.email,
employees.phoneno, employees.department, employees.title,
employees.employee FROM employees, engineers WHERE employees.employee =
engineers.employee AND engineers.costcntr IN ('63100');

the backend succeeds without a problem.

The table definitions are as follows:

Table = employees
+----------------------------------+----------------------------------+-------+
| Field | Type
| Length|
+----------------------------------+----------------------------------+-------+
| employee | varchar() not null
| 10 |
| lastname | varchar() not null
| 20 |
| firstname | varchar() not null
| 16 |
| reportsto | varchar() not null
| 10 |
| email | varchar() not null
| 50 |
| phoneno | varchar() not null
| 16 |
| department | varchar() not null
| 32 |
| title | varchar() not null
| 32 |
+----------------------------------+----------------------------------+-------+
Index: k_employees

Table = engineers
+----------------------------------+----------------------------------+-------+
| Field | Type
| Length|
+----------------------------------+----------------------------------+-------+
| employee | varchar() not null
| 10 |
| costcntr | varchar() not null
| 5 |
+----------------------------------+----------------------------------+-------+
Index: k_engineers

The backend is the Beta1 release of 6.4 running on
Linux slackware 2.0.35 with gcc 2.7.2.2 on a Pentium

The backend was built without any options...just
./configure ; make ; make install.
I hope this can be fixed as I love the feature richness
of postgresql.
