Reproducible on devel, 5.1.4, and 5.0.17, but the latter handles it better.
And while testing this on devel, I came across another one:
$ echo $BASH_VERSIbash: xmalloc: stringvec.c:40: cannot allocate
15227146888 bytes (2510848 bytes allocated)
$
$ echo $BASH_VERSIOSegmentation fault (core dumped)
$
I hit tab a few times to get the segfault.
