[Bug c++/15736] New: internal compiler error: in force_decl_die, at dwarf2out.c:12441

[carlo at gcc dot gnu dot org]

This bug, or rather a very similar one was fixed not long ago.
But it appears still to exist in todays compiler :/

To reproduce compile this:

class sbll_node_ct;

class sbll_base_ct {
protected:
  sbll_base_ct(void) { }
  ~sbll_base_ct(void) { }
  class sbll_node_ct* next;
};

class sbll_list_ct: private sbll_base_ct {
protected:
  using sbll_base_ct::next;
};


by doing:

>g++-cvs-3.5 -c -g test.cc
test.cc:12: internal compiler error: in force_decl_die, at dwarf2out.c:12441
Please submit a full bug report,

A slightly simpler test case:


struct B {
  int n;
};

struct A : B {
  using B::n;
};

Devang Patel, can you look into this as I think this is caused by your patch:
2004-01-27  Devang Patel <dpatel@apple.com>

        * Makefile.in (dwarf2out.o): Depend on input.h
        * dbxout.c (dbx_debug_hooks): Add new empty hook for
        imported_module_or_decl.
        (xcoff_debug_hooks): Same.
        * sdbout.c (sdb_debug_hooks): Same.
        * vmsdbgout.c (vmsdbg_debug_hooks): Same.
        * debug.c (do_nothing_debug_hooks): Same.
        (debug_nothing_tree_tree): New function.
        * debug.h (gcc_debug_hooks): New hook, imported_module_or_decl.
        * dwarf2out.c: Include input.h.
        (dwarf2_debug_hooks): Add new hook for imported_module_or_decl.
        (remove_child_TAG): New function.
        (dwarf_tag_name): Handle DW_TAG_imported_module.
        (gen_subprogram_die): Equate decl number to declaration die. Do not
        remove all children dies while reusing declaration die for definition.
        Instead, selectively remove only formal parameters.
        (gen_variable_die): Equate variable decl to declaration die.
        (gen_field_die): Equate field decl to line number.
        (force_namespace_die): Replace it with ...
        (force_decl_die): ... this.
        (force_type_die): New function.
        (setup_namespace_context): Replace use of force_namespace_die() with
        force_decl_die().
        (gen_namespace_die): Same.
        (dwarf2out_imported_module_or_decl): New function.

If following patch is reverted than it fixes this ICE.
  http://gcc.gnu.org/bugzilla/show_bug.cgi?id=15736

But that patch was applied to fix Ada bootstrap. Andrew, do you have Ada setup to see if this patches 
still causes trouble with Ada?

Thanks.

Which patch, you only gave a link to this bug again?  Also Ada is broken on the mainline because of
the tree-ssa merge so I cannot test Ada :(.

Thanks,
Andrew
