FWIW, I see failures on i386-unknown-netbsdelf1.6 too:
   FAIL: 17_intro/header_csetjmp.cc (test for excess errors)
   FAIL: 17_intro/header_cstdlib.cc (test for excess errors)
   FAIL: 17_intro/header_cwchar.cc (test for excess errors)
   FAIL: ext/hash_set.cc (test for excess errors)

They all fail with the ICE
   /gcctmp/gcc040116/gcc/libstdc++-v3/testsuite/17_intro/header_csetjmp.cc:29: internal compiler error: virtual array alias sets[4]: element 4 out of bounds in get_alias_set_entry, at alias.c:218
