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

------- Comment #2 from reichelt at gcc dot gnu dot org 2008-09-30 21:33 -------
The second (weakref) case has been fixed on mainline and the 4.3 branch
by the patch for PR37645. The attribute is ignored and the code compiled:
bug.c:1: warning: 'weakref' attribute ignored
The first (alias) case still crashes, though.
