    Coralie,

    Soon after releasing 101.4 we found an error in sgftops.c. The error had
    been there for a while, and it manifested itself only rarely so we figured
    it could wait until the next release. It may or may not be related to
    your symptom, but I am attaching a patch file that fixes it. I suggest
    that you run the patch (or just edit sac/utils/sgftops.c as it is very
    simple), compile it (one does not have to rebuild SAC), put the executable
    in your path and see if it helps.

    Let me know.
