I cleared out the directory, started over and recopied the files in place.  I
get a clean execution with no errors with -O1 using g77.  When I rm *.o and
recompile with gfortran execution of ./xeigtstd < ded.in results as follows:

   -O1   execution hangs in infinite loop
   -O0    DES:    1 out of  3270 tests failed to pass the threshold
          DSX:    1 out of  3500 tests failed to pass the threshold
   -01   with numerous -fno-OPTIMIZATIONS it still hangs

When I go to the LAPACK directories and run the clean builds and make testing,
xeigtstd < ded.in completes execution.  The only difference between this and the
 above hangs is that the MATGEN and BLAS routines are compiled into static
libraries as an intermediate step.  I am using a script to completely rm all .o
and libraries before rebuilding LAPACK.

Target: i686-pc-linux-gnu
Configured with: ../gcc/configure --prefix=/home/jerry/usr --enable-languages=c,f95
