[New-bugs-announce] [issue27325] random failure of test_builtin

[Xavier de Gaye]

New submission from Xavier de Gaye:

Not sure if this is relevant, I am using:
    readline 6.3
    ncurses 6.0

The test runs fine when run alone, with the 8991930 random seed:

$ ./python -bb -E -Wd -m test -r -w -uall --randseed 8991930
