[Bug fortran/28735] New: Crash in resolve.c - related to contents of .mod

[adsspamtrap01 at yahoo dot com]

Encountering segfault when compiling a very simple .F and 
"use" -ing a certain .mod file.  

Encountered crash on gfortran 4.1.0 and 4.1.1.  Patch below 
is against 4.1.1.

I've pared down the .mod file from it's original size; I've 
removed as much as I can such that the crash occurs.  Note 
that the crash doesn't happen if "('imaxf' 0 50 )" is removed 
from the module.  

Crash occurs because e->symtree is NULL in 
resolve_ref()/find_array_spec().  

Patch to fix crash (needs review; I don't know gcc/gfortran):

vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv

Err, nix the "use bdy_comm" line.  Sample fortran code 
should read:

      subroutine sub( myint )

      use domdec

      return
      end

Sorry, no.  It is from the COAMPS project 
(http://www.nrlmry.navy.mil/coamps-web/web/home).  
Source for the project is available to anyone, but you 
have to sign (!) a EULA to get the code; part of the 
EULA states that you can't redistribute the code.

OK, I've put together some sample .F files that demonstrate the 
crash without compromising the COAMPS IP.  Compile dummydomdec 
and dummybdy_comm, then try to compile sub and you'll get the 
crash.

Andrews,

The proposed fix is a good start but I am going to go at this one carefully -
the ICE goes away if the PRIVATE in dummybdy_com is removed; I want to find out
why this is first.

------- Comment #7 from pault at gcc dot gnu dot org  2006-08-17 14:57 -------
(In reply to comment #6)
OK I understand it now.  The PRIVATE declaration prevents references to 'a' and
'b' from being resolved, when USEing dummybdy_comm, because it suppresses the
symtree.  This is demonstrated by making 'a' and 'b' public in module
dummybdy_comm, or by inverting the order of the USE statements in 'sub' (yes,
they get USEd in inverted order!).

Your proposed patch is OK but the subsequent check on e->symtree is now
redundant and should be removed. I am just now regtesting the result and will
submit mit it and the testcase below tonight.

Thanks for the report.

Paul

        * gfortran.h : Eliminate gfc_dt_list structure and reference
        to it in gfc_namespace.
        * resolve.c (resolve_fl_derived): Remove the building of the
        list of derived types for the current namespace.
        * symbol.c (find_renamed_type): New function to find renamed
        derived types by symbol name rather than symtree name.
        (gfc_use_derived): Search parent namespace for identical
        derived type and use it, even if local version is complete,
        except in interface bodies. Ensure that renamed derived types
        are found by call to find_renamed_type. Recurse for derived
        type components.
        (gfc_free_dt_list): Remove.
        (gfc_free_namespace): Remove call to previous.
        * trans-types.c (copy_dt_decls_ifequal): Remove.
        (gfc_get_derived_type): Remove all the paraphenalia for
        association of derived types, including calls to previous.
        * match.c (gfc_match_allocate): Call gfc_use_derived to
        associate any derived types that are being allocated.

        PR fortran/20886
        * resolve.c (resolve_actual_arglist): The passing of
        a generic procedure name as an actual argument is an
        error.

        resolving references.

        * primary.c (match_variable): Return MATCH_NO if the symbol
        is that of the program.

        derived type component expressions other than another derived
        type constructor.

        * expr.c (find_array_section): Correct errors in
        the handling of a missing start value for the
        index triplet in an array reference.

        PR fortran/18111
        * trans-decl.c (gfc_build_dummy_array_decl): Before resetting
        reference to backend_decl, set it DECL_ARTIFICIAL.
        (gfc_get_symbol_decl): Likewise for original dummy decl, when
        a copy is made of an array.
        (create_function_arglist): Likewise for the _entry paramter
        in entry_masters.

        (generate_dependency_declarations): New function.
        (generate_local_decl): Call previous if not either a dummy or
        a declaration in an entry master.
