I haven't analyzed the issue thoroughly, but it's quite plausible
you're right.

Problem of GDB asking to read packetsize/2 has also be detected  with
the Valgrind gdbserver, which expects that
    nr_bytes_requested_in_m_packet*2 + 4 <= packetsize
but GDB only guarantees
     nr_bytes_requested_in_m_packet*2 <= packetsize

If you don't plan on contributing fixes, could you file (separate) bug
reports for these, so they don't get lost?

Have these been filed ? Not seen ...


Haven't come around to do it yet, sorry.
I also wanted to check with valgrind before....

regards,
chris
