 Could you provide a trace using "set debug remote 1"?

 Why wrongly?  Do you mean that it shouldn't be executed, or that it is
 executed incorrectly?
 
 I really wouldn't have expected you to be triggering that code with an
 0x45 byte text section, anyway.  That's plenty small enough to fit in
 one packet.  Is get_memory_write_packet_size returning something tiny?
