Sounds like a big non-sequitur.  scm_remember_upto_here_* is for keeping
SCM values active (including in registers).  Any conversion of an SCM
value to some other data depending on it will not protect the SCM value
as such and may lead to collection/finalization of the SCM cell (calling
guardians, removing from weak hashtables and so on).
