[Bug c++/28112] New: [4.0/4.1/4.2 regression] ICE with invalid argument in attribute

[reichelt at gcc dot gnu dot org]

The following invalid code snippet causes an ICE since GCC 3.4.0:

===============================================
struct A {} __attribute__((aligned(;)));
===============================================

bug.cc:1: error: expected primary-expression before ';' token
bug.cc:1: error: expected `)' before ';' token
bug.cc:1: error: expected `)' before ';' token
bug.cc:1: internal compiler error: tree check: expected tree_list, have
error_mark in handle_aligned_attribute, at c-common.c:4698
Please submit a full bug report, [etc.]

This happens more or less with all attributes that take an argument list
and seems to be C++ specific.

Testing a patch.
