Reproducible on devel, 5.1.4, and 5.0.17, but the latter handles it better.

Thanks for the report. It's not the parser, or a real `syntax check'; it's
the history code trying to determine which delimiter to use when adding it
to the history list.

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.

I can't reproduce this.
