Possibly related to enabling the nghttpx server recently:
c8b76ff #19723
But, some issues happen with OpenSSL and openssl-quic
where it has been enabled for a long time.
valgrind is installed for the curl test jobs since
c1deea4 #19719. It
should make no difference for pytests.
Maybe the 4 runtests valgrind tests leave the nghttpx server
in a bad state?
valgrind H3 tests also fail the test itself, e.g. here:
https://github.com/curl/curl/actions/runs/19806175180/job/56740663348
I expected the following
Clean test run.
curl/libcurl version
master (recent 3-4 days)
operating system
Linux
