                    -fcheck=pointer
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED

        ReportedBy: burnus@gcc.gnu.org


FGSL version 0.9.3 from
http://www.lrz.de/services/software/mathematik/gsl/fortran/

With gfortran 4.7 and with gfortran 4.6.1 20110801 (rev. 177033), I get:

  api/siman.finc:99:0: internal compiler error: in fold_convert_loc,
                       at fold-const.c:2026

It works with 4.5.3 20110428 [rev. 173117].
