Re: missing GC protection in Fbyte_code

[Richard Stallman]

    As far as I can tell, all the cases in Fbyte_code that call
    record_unwind_protect should protect against GC like the
    Bunwind_protect case.  I don't know why we missed that originally.

The comment is wrong: record_unwind_protect cannot GC.
So I think the right change is to delete the gc protect
stuff from the Bunwind_protect case.

Stefan was the last one to change that code.  Maybe the old
record_unwind_protect could GC in the past, but not now.  Stefan, is
that what happened?
