Regression test failure on v7.0.3?

I just downloaded and compiled postgresql v7.0.3 afterwards I ran the regresion tests. First, I did a 'make runcheck' and everything was 'ok'. Then I ran 'make bigcheck'. It failed on "test random".

Deleted all the source tree and untarred from the tar ball a new copy. Then went and editied ../src/include/config.h.in and modified the BLCKSZ to 16384. ran 'configure --with-x' and then 'make' and 'make install'.

I went again and reran the regression test. It *passed* both runcheck and bigcheck.

The I ran runcheck again. This time it failed on "test random".

$ diff expected/random.out results/random.out
28c28,29
< (0 rows)

Anyone else see this? Is this a problem? I am running on RedHat 7.0

Thanks,
Robert
