--- Comment #3 from Martin Losch <mlo...@uni-bremen.de> 2011-02-01 17:30:56 UTC --- gfortran -O3 -c exch2_uv_agrid_3d_rl.f gives the same error gfortran -O2 -c exch2_uv_agrid_3d_rl.f works for this file (for others that are similar I need -O1). I have to admit that I have never ventured into building gfortran/gcc myself, but downloaded the binaries for Mac OS X 10.6 here: <http://hpc.sourceforge.net/>. I just posted this bug, because I thought it would be useful. If my rebuilding gfortran from source is required I won't be of much help. (In reply to comment #2) > Works for me on x86-64-linux. There is some possibility that the patch for PR > 45700 fixed that issue (committed: 2010-11-26) - at least that is the only > thing which vaguely goes into the direction of the ICE (internal compiler > error). > > Thus, one possibility would be to try a newer version. > > Other than that: > > gfortran -v -save-temps -Wunused -Wuninitialized -fsecond-underscore > -fconvert=big-endian -ffixed-line-length-132 -O3 -funroll-loops -c > > You use a large number of options. Can you cut down the number of options and > see whether, e.g., -O2 or -O1 or -O0 is enough to trigger the issue?
