On OS X 10.11.2 Beta (15C31f),
TestCompletion.CommandLineCompletionTestCase.test_symbol_name_dwarf is failing
intermittently (2 out of 3 times on my system) when the parallel test runner is
used.

Test trace follows:

with pid: 48966
stdout: rm -f  main.o main.d main.d.tmp main.dwo   
rm -f -r "a.out.dSYM"
rm -f "a.out"

stderr: 
retcode: 0
