Follow-up Comment #4:

I have confirmed this issue.  The Fortran code from SLATEC is in error.  The
reason it has rarely been a problem is that Octave usually links in the erf()
function from the C math library.  It is only when that version is unavailable
that we switch over to the Fortran version that Octave ships in libcruft. 
This does occasionally happen as has been reported on the MinGW platform in
reference to a different bug.  I will take this up on the Octave mailing list
soon for the best way to implement a fix.
