--- Comment #3 from Dominique d'Humieres <dominiq at lps dot ens.fr> 2012-05-09 12:33:16 UTC --- As a temporary work around for aermod.f90, you can compile it with '-fprotect-parens -Ofast' (it does not work for the code in pr53217). Also a patch has been submitted at http://gcc.gnu.org/ml/gcc-patches/2012-05/msg00607.html
