The number in parentheses is simply how many times Bash has been compiled
in the current source tree.  If you apply a new patch and run "make"
again, the number goes up.  It's not actually a different version.

Your interactive shell is not Bash (or it's a very OLD Bash), so the
{1..200} was not expanded.  That's why this test failed.

Run it again from within Bash.

And for god's sake, don't do vulnerability testing as root.
