I can reproduce the failure manually now, in that test environment.

I tried different values for the printf amount (4096, 2048, 16386). I also
increased the buffer size in the modpipe.c utility. Nothing like this helped.
I'm trying now to get rid of the modpipe intermediary, to see if that's the
thing getting in the way of the flow of data.

Title:
OpenSSH autopkgtests do not like tilde character in its version string
(e.g. ~ppa1)
Status in openssh package in Ubuntu:
New
Bug description:
Starting with Noble, the openssh autopkgtest "regress" (specifically
"integrity.sh") fails when the version string contains a tilde
character, such as "~ppa1".
In such case, it would fail with a log like this:
