Ben,
I have tried the gfortran 4.2 you linked to, but nothing changed, I  
still get exactly the same crashes as with g95.
Just for curiosity I also tried rebuilding Octave 3.2.3 with g95 and  
qrupdate 1.1.1 and everything went fine, this seems
to indicate the bug is neither in qrupdate nor in Apple's BLAS/LAPACK  
but somewhere in Octave or in the way I am building.
I will follow the instuctions by Jaroslav for debugging with valgrind  
tomorrow.
