Subject: Re: How and when to use GCPRO?

There is a simple general rule for which Emacs C functions can GC:
those that can directly or indirectly call eval. To make Fcar call
eval would be a rather shocking and drastic change. There is no need
to take precautions today against the possibility of such a drastic
change in the future.
