           Summary: [4.7 Regression] ICE with
                    gfortran.dg/module_write_1.f90
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Keywords: ice-on-valid-code
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: bur...@gcc.gnu.org
        ReportedBy: bur...@gcc.gnu.org
            Blocks: 48588


My recent patch for PR 48588 (submitted patch:
http://gcc.gnu.org/ml/fortran/2011-04/msg00206.html ), Rev. 172718, causes a
regression:

For gfortran.dg/module_write_1.f90:

f951: internal compiler error: in gfc_enforce_clean_symbol_state, at
fortran/symbol.c:3426

#0  gfc_enforce_clean_symbol_state () at gcc/fortran/symbol.c:3426
#1  0x0000000000526ee1 in next_statement () at gcc/fortran/parse.c:889
#2  0x000000000052a88e in gfc_parse_file () at gcc/fortran/parse.c:4329


The problem is that gfc_commit_symbol/-s or gfc_undo_symbols has not been
called.
