So with patch I still see couple of ICEs remaining:

One reduced test-case:
$ cat 1.ii
template <char...> int operator"" _abc();
template <> int operator"" _abc();
$ ./xg++ -B. 1.ii -c
hash table checking failed: equal operator returns true for a pair of values
with a different hash value
1.ii:2:33: internal compiler error: in hashtab_chk_error, at hash-table.h:1022
2 | template <> int operator"" _abc();

I'm planning to disable the sanitization of the 2 hash tables now.
@Jason: can you please take a look at the remaining test-cases?
