Issue Description:

Seeing this in the 5.1 bot – https://ci.swift.org/job/oss-swift-5.1-incremental-RA-linux-ubuntu-16_04//260/console

00:58:16.689 The following tests FAILED:
00:58:16.689      1 - TestFoundation (SEGFAULT)

I don't see any Foundation commits in the commit list, and its not clear which specific test case failed, so I'm a bit stumped. Is there a transient memory corruption issue somewhere?

Another example, which blocks submission of a change to swift-corelibs-libdispatch:

Still happening in PR tests: https://ci.swift.org/job/swift-PR-Linux/12156/

I think this is in TestXMLDocument.test_xpath. All the logs I've seen end like this:

09:48:26 Test Case 'TestXMLDocument.test_xpath' started at 2019-03-18 11:48:26.632
09:48:26 
09:48:26 
09:48:26 0% tests passed, 1 tests failed out of 1

The other tests show "passed", but not this one.
