The code would assume that SubstExpr() cannot fail on concept specialization. This is incorret - we give up on some things after fatal error occurred, since there's no value in doing futher work that the user will not see anyway. In this case, this lead to crash. The fatal error is simulated in tests with -ferror-limit=1, but this could happen in other cases too.
