Given following log snippets, their explanation, and nothing else, explain what failure, if any, occurred during build of this package.

  Snippets are in a format of [X] : [Y], where [X] is a log snippet, and [Y] is the explanation.

  Snippets are delimited with '================'.

  Drawing on information from all snippets, provide a concise explanation of the issue and recommend a solution.

  Explanation of the issue, and recommended solution, should take a handful of sentences.

  Snippets:

  [FAIL: Test-proxied-https-auth.px
FAIL: Test-proxied-https-auth-keepalive.px]: [The snippet shows two failed unit tests. Unfortunately I don't have any verbose output here.]

Issue: After some investigation, I figured that these tests fail when max optimization during build is enabled.
Resolution: Currently, unit tests are turned off during the build. But disabling optimizations would work as well.
