[Bug c++/35329] New: [4.2/4.3/4.4 regression] ICE with invalid template class after #pragma interface

[reichelt at gcc dot gnu dot org]

The following invalid code snippet triggers an ICE since GCC 4.2.0:

====================================================
#pragma implementation
#pragma interface

template<void> struct A
{
  A() {}
};
====================================================

bug.cc:4: error: 'void' is not a valid type for a template constant parameter
bug.cc: In constructor 'A<<declaration error> >::A()':
bug.cc:6: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]

Fixed on the trunk by Jason's patch

2009-03-17  Jason Merrill  <jason@redhat.com>

        * decl.c (grokfndecl): Set DECL_CONTEXT on parms.
        (duplicate_decls): Adjust DECL_CONTEXT of newdecl's parms.
        * pt.c (check_explicit_specialization): Likewise.
        (tsubst_copy) [PARM_DECL]: Return a dummy parm if we don't have a
        local specialization.
        * tree.c (cp_tree_equal) [PARM_DECL]: Check type and index, not name.
        * decl2.c (parm_index): New fn.
        * semantics.c (finish_decltype_type): Don't use describable_type.
        * mangle.c (write_expression): Likewise.  Mangle ALIGNOF_EXPR.
        Give a sorry for unsupported codes rather than crash.  Mangle
        conversions with other than 1 operand.  New mangling for PARM_DECL.
        * operators.def (ALIGNOF_EXPR): Mangle as "az".
