That is basically what you do in GNUTLS and it is what I consider a
good fallback action.

It is not a really hard error but may indicate other problems.  This
is a problem of the caller and not necessary of libgcrypt, so I don't
call BUG () as in other places.  Consider you have widely deployed an
application and suddenly (e.g. due to a date problem) it aborts all
the time due to such an abort - you won't have a chance for a good
workaround even if is only a minor problem or no real problem at all.

Ask the Ariane engineers about such stuff ;-)
