[Bug 2060967] Re: noble/rsync buffer overflow detected

[Mitchell Dzurick]

The debian patch looks promising in my local testing. I uploaded a test
package to run dep8 tests against. If those look green I'll submit my MP
and get it in ASAP.

Bug description:
  Hi,

  running the following test case in a current (today/2024-04-11) Noble
  install leads to a "buffer overflow detected":

  $ rsync -F --delete-after --archive /etc/fstab 127.0.0.1:/tmp/
  *** buffer overflow detected ***: terminated
  rsync: connection unexpectedly closed (11 bytes received so far) [sender]
  rsync error: error in rsync protocol data stream (code 12) at io.c(231) [sender=3.2.7]

  Original use case for the above striped down rsync options is the
  ansible module "synchronize".
