[Bug c/35434] New: [4.2/4.3/4.4 regression] ICE with attribute alias/weakref

["reichelt at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

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

===============================================
typedef int i __attribute__((alias("j")));
===============================================

bug.c:1: internal compiler error: in make_decl_rtl, at varasm.c:1267
Please submit a full bug report, [etc.]

Before GCC 4.2.0 we got the error:
bug.c:1: error: 'i' defined both normally and as an alias


A similar code snippet causes a crash in a different location:

===============================================
typedef int i __attribute__((weakref("j")));
===============================================

bug.c:1: internal compiler error: in lhd_set_decl_assembler_name, at
langhooks.c:160
Please submit a full bug report, [etc.]

Before GCC 4.2.0 we got the error:
bug.c:1: error: weak declaration of 'i' must be public
bug.c:1: error: 'i' defined both normally and as an alias
