I looked at gdb.log, and found these FAILs:
...
(gdb) maintenance selftest copy\a_\a
copy_bitwise          copy_integer_to_size
(gdb) maintenance selftest copy_PASS: gdb.gdb/unittest.exp: 
test_completion: tab complete "maintenance selftest copy"
FAIL: gdb.gdb/unittest.exp: test_completion: tab complete "maintenance 
selftest copy" (clearing input line) (timeout)
^Cmaintenance selftest copy_bit\aQuit
(gdb) FAIL: gdb.gdb/unittest.exp: test_completion: tab complete 
"maintenance selftest copy_bit"
Quit
...

This looks like the well-known 
https://sourceware.org/bugzilla/show_bug.cgi?id=27813 to me.

Maybe we should move the completion tests out of this test-case?

Thanks,

Saw this fail a couple of other times as well. Latest:
https://builder.sourceware.org/buildbot/#builders/170/builds/1088

Do you propose to split out the test_completion from
gdb.gdb/unittest.exp or to just remove it from the list of TESTS for
the buildbot make check-gdb target?

Cheers,

Mark

Hi Mark,

I did look at that failure, but the failure mode is different:
...
(gdb) maintenance selftest copy\a_\a
copy_bitwise          copy_integer_to_size
FAIL: gdb.gdb/unittest.exp: test_completion: tab complete "maintenance 
selftest copy" (second tab) (timeout)
Quit
...

I don't know what's causing that.  Maybe some system readline vs. gdb 
readline issue, just a guess.

The first.
