Re: [Fink-users] gfortran from gcc43-4.3.3-100 throwing "Illegal instruction" errors on 10.5.6 G4

[Jack H. <ho...@br...>]

Alexander,
    I just rebuilt gcc43 and octave on a dual G5 running
10.5.6 with Xcode 3.1.2. Everything builds normally here.
Are you sure you don't have some non-fink software installed
that is confusing the fink builds? I've had no other reports
of this problem.
                 Jack
