move(somepchar^,pchar(ansi_str_dest)^,len);
doesn't check fpc_ansistr_unique. So it works only if ansi_str_dest has
only one reference; or both strings will be modified (because no
copy-on-write happens).
At least, that's what I get to see, if I compile with -al and look at
the assembler.

I had not checked it but I think you can use the typecasting:
move(somepchar^,pchar(ansi_str_dest)^,len);
as typecasting an ansistring to a pchar should return (repeat "I
think") a pointer to ansi_str_dest[1], and if length(ansi_str_dest)=0
then the pointer should be $00000001 :-? which should not raise any
kind of range check.
