I think this is important. It seems that the problem is caused by an
attempt to calculate the eigenvalues and this attempt is triggered by
"iprint."

The program crashes (AIX) or writes the warning message (Linux) at the
point where it is supposed to print (iprint=X) "relevant physical
quantities to standard output ..." -- and very reproducible for any X.
