caller GCPROs?

Is there any particular reason for this rather obvious lie ('This function can GC') at insdel.c:2644? --------------- 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); } ----------------- one consequence is the following in buffer_insert_string_1 at insdel.c:2457 ----------------- /* theoretically not necessary -- caller should GCPRO. #### buffer_insert_from_buffer_1() doesn't! */ GCPRO1 (reloc); ----------------- -- Gunnar Evermann Speech, Vision & Robotics Group Engineering Department Cambridge University
