Errmm... I'm not so sure it's a bug!

OK, that's the odd-looking thingie. What does it actually contain?
>> foreach c foo [
[ use [cc] [
[ cc: to-char c
[ print [c "^-" enbase/base to-string cc 16 "^-" cc]
[ ]
[ ]
1 01
35 23 #
69 45 E
35 23 #
123 7B {
48 30 0
49 31 1
50 32 2
51 33 3
125 7D }
So, it appears that join took the content of the block, converted it
to a string, and concatenated the bytes of the string onto the binary
value that was its first argument, and gave back that result.
Compare and contrast with
>> join #{32} [1234]
== #{3231323334}
and
>> foo: probe join #{012345} #{0123}
#{0123450123}
== #{0123450123}
