---------------
Charcount
buffer_insert_from_buffer_1 (struct buffer *buf, Bufpos pos,
struct buffer *buf2, Bufpos pos2,
Charcount length, int flags)
{
/* This function can GC */
Lisp_Object str = make_string_from_buffer (buf2, pos2, length);
return buffer_insert_string_1 (buf, pos, 0, str, 0,
XSTRING_LENGTH (str), flags);
}
That's no lie. buffer_insert_string_1() can not only GC, but invoke
arbitrary Lisp code! Remember {before,after}-change-functions.
