I don't think so.  if `scm_remember' takes an SCM, then the compiler
has all the rights to reuse the register (or the stack word) that held 
`str'.

but if you pass a pointer to `str', then the compiler has (or at least
it can be hoped that it has) to make sure that the pointer really
points to a valid location that contains `str', and at least for the
life expectancy of `str'.
