Running layout tests in this build:
https://build.chromium.org/p/tryserver.chromium.linux/builders/linux_chromium_rel_ng/builds/451755

Two CSP-related directive parsing tests failed, with an internal server error being reported from the local Apache server.

(Unexpected Failures:
* http/tests/security/contentSecurityPolicy/directive-parsing-03.html
* http/tests/security/contentSecurityPolicy/source-list-parsing-04.html)

The tests attempt to request a document from the server, which should return a document with an invalid CSP header. (Contains \x07, \x08 or \x09 characters embedded in the header).

In this instance (presumably this doesn't happen all the time), the running server failed to return the document, and instead failed and returned a 500 ISE.

The error logs from the server show this:
