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.

Thanks,
