New Revision: 18505

Modified:
   seismo/3D/SPECFEM3D_GLOBE/trunk/flags.guess
Log:
changed -O3 to -O2 by default for gfortran because of an internal error in gfortran (some versions crash with -O3 because of the number of arguments in some subroutine calls; they should not crash, but they do; reducing the optimization level to -O2 fixes the problem)
