And what happens when:
same? b b/2
is done? This:
REBOL caused a stack fault in module REBOL.EXE at 015f:00435703.
Registers:
EAX=00c04838 CS=015f EIP=00435703 EFLGS=00010297

ECX=00000013 DS=0167 ESI=00c04838 FS=4387
EDX=0000002f ES=0167 EDI=00c04838 GS=0000
Bytes at CS:EIP:

Is this a bug? I've send it to feedback, just in case.

I just wonder, when if ever will such bugs be resolved? They are so
essential. It seems to me that rebol's aproach "everything's-a-reference"
gets pretty complicated sometimes and that it's hard to keep concepts clean
sometimes. It's strange to see notes as Elan's in his book about 2.2 and
above unstable behavior of extended contexts. I am just curious if GC bugs
reported were resolved ....
... still missing bug database presence on some place ...

Part of my definition of "high-level language" is the clause, "and if
you do something it doesn't like (regardless of how dumb or obscure it
MIGHT be), it won't blow up in your face".
By that definition, at least, this is a bug.
Nicht Wahr?
