Did you try to compile this file without optimization (as is indicated in:
http://www.netlib.org/lapack/faq.html#1.26)? The code in the ?lam*.f files is
used to determine the machine precision (which could be done easily in Fortran >
77), and any level of optimization other than -O0 usually causes infinite loops.
