The following invalid code snippets triggers an ICE since GCC 4.1.0:
=========================================
struct A
{
void x[1] __attribute__((packed));
};
=========================================
bug.c:3: error: declaration of 'x' as array of voids
bug.c:3: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in handle_packed_attribute, at c-common.c:4653
Please submit a full bug report, [etc.]
Also other attributes applied to invalid variables cause ICEs
in various places, e.g.
=================================================
typedef char x[N] __attribute__((aligned(4)));
=================================================
bug.c:1: error: 'N' undeclared here (not in a function)
bug.c:1: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in build_variant_type_copy, at tree.c:4180
Please submit a full bug report, [etc.]
=================================================
void x[1] __attribute__((vector_size(8)));
=================================================
bug.c:1: error: declaration of 'x' as array of voids
bug.c:1: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in handle_vector_size_attribute, at c-common.c:6070
Please submit a full bug report, [etc.]
=================================================
void x[1] __attribute__((may_alias));
=================================================
bug.c:1: error: declaration of 'x' as array of voids
bug.c:1: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in decl_attributes, at attribs.c:355
Please submit a full bug report, [etc.]
