    Description

      Analysis of the last 240 CI runs for Ubuntu 10.04 (builds 2352 to 2591) shows that this test has a stable failure in tst_QUdpSocket::multicastTtlOption(), a variety of unstable crashes and failures (see attachment), and inconsistent skipping of at least one test function (see second example below).

      Unable to find source-code formatter for language: stable failure. Available languages are: actionscript, ada, applescript, bash, c, c#, c++, cpp, css, erlang, go, groovy, haskell, html, java, javascript, js, json, lua, none, nyan, objc, perl, php, python, r, rainbow, ruby, scala, sh, sql, swift, visualbasic, xml, yaml
