Thank you for the very nice and clear test case!  That is much
appreciated.

What version of bash are you using?

  echo $BASH_VERSION

I could not reproduce this problem with the bash 4.3.42 on my system.
Nor with 4.2.37 on another system.  Nor 3.2.39 on a much older system.

I didn't try every possible version of bash but I presume that this is
a version specific bug that has been fixed in later versions.
