[DECtalk] a very interesting bug I just found

[Mohamed]

Hi guys, I just now found the craziest bug ever in dectalk. Well, maybe 
not craziest, but definitely strange, and I'm wondering if people have 
found this at all and what could be going on.
It effects all versions.
Have a listen to this little thing I created.

[deh<800,25>]
[d<60>] [ey<800,34>] [r<1000,30>].
If you look at the code, you'll notice that there's a middle a in there 
that dectalk, for some reason, completely skips over. I found that 
changing the r to an rr solves the problem, but I'm wondering just 
what's going on that's causing this?
Thanks.
