the "4*" prefix is needed (it's not multiplication, just an ugly
Fortran feature), any integer will do as the second. Or you can supply
4 different integers separated by commas.
Prior to doing so, please apply this patch:

or delete the *.out files after each try, otherwise a segfault may
escape your attention.
If you can't produce a failure this way, the problem is probably not
in qrupdate.

OK, I used 'data seed /4*23/' and got some test failures, and even in tests that do pass some residuals are not very small
