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.
