I can also trigger this ICE with a cross from x86_64-pc-linux-gnu to
alpha-linux-gnu:
#0 htab_find_with_hash (htab=0x0, element=0x7fffffffcb30, hash=484198) at
../../gcc-svn/trunk/libiberty/hashtab.c:600
#1 0x0000000000c2dbb6 in lookup_scoped_attribute_spec (ns=Unhandled dwarf
expression opcode 0xf3
) at ../../gcc-svn/trunk/gcc/attribs.c:325
#2 0x0000000000a91bc9 in comp_type_attributes (type1=0x2aaaae8199d8,
type2=0x2aaaae819930) at ../../gcc-svn/trunk/gcc/tree.c:4353
#3 0x0000000000a91f0b in build_type_attribute_qual_variant
(ttype=0x2aaaae819930, attribute=Unhandled dwarf expression opcode 0xf3

The problem is dereference of htab (=0x0) in htab_find_with_hash.
