[Mihai Parparita]

http/tests/incremental/split-hex-entities.pl appears to occasionally crash (due to a failed assertion) with debug builds: http://test-results.appspot.com/dashboards/flakiness_dashboard.html#showAllRuns=true&showExpectations=true&master=ChromiumWebkit&tests=http%2Ftests%2Fincremental%2Fsplit-hex-entities.pl

The assertion is:
ASSERTION FAILED: !m_pushedChar1
(third_party/WebKit/WebCore/platform/text/SegmentedString.h:210 int WebCore::SegmentedString::numberOfCharactersConsumed() const)
[9796:9796:1440464744106:ERROR:process_util_posix.cc(106)] Received signal 11
