qp() in Octave 3.0.0 returns result egregiously violating input constraints

ok, I pulled sources to my intel and ppc based Macs (each running OSX  
10.5.2) and built both branches on each.

The "release-3-0-x" fails on the intel box.

result =  5.4445e+58

The qp example appears to work on release-3-0-x running on the ppc.

result =  2.7676e-06

I get identical answers running the default branch on both my intel  
and ppc based macs.
