erroneous energies with lapack_double.o compilation

[jasius]

Hi, I am getting a very strange behavior, when I compile with (lapack_double.o in vasp.4.lib) - and I need to do that to make that insidious ZHEGV error to go away. So when I compile my 4.6 with lapack_double.o, my energies are about x8 from where they were when I used external LABPACK. I got test files from collegues with the bench energies and my external LABPACK energies agree, but build in LAPACK yiels about 8 times higher energies
thanks

please first of all try to find out
1) which of the results are the correct ones
2) if the serial and the parallel executables of vasp show the same error (or if eg the factor in the energy scales with the number of CPUs?)
--> please run eg. one of the vasp-workshop (sessions 1-4) examples

to check which of the 2 lapacks yields the correct energy (the numbers may not be consistent up to the very last digit, but certainly they will be close enough to one of your results so you can check which one is the correct one).
