[ecasound] Problems with only one input with more than one chain

Greetings,

If I run ecasound with the following ECS file and let it run to the end
(file ends), then do EIAM command "setpos 0", then "t"...

-a:1 -f:16,1,48000 -i:Guitar.wav,
-a:1 -f:16,2,48000 -o:alsa,hw:0
-a:1 -erc:1,2 -ea:100 -epp:50 -efl:20000 -efh:4

...everything works fine.

But if I take the same ECS file and add another chain to "Guitar.wav"
and let it run till the end (file ends), then do EIAM command "setpos
0", then "t"...

-a:1,1.1 -f:16,1,48000 -i:Guitar.wav,
-a:1,1.1 -f:16,2,48000 -o:alsa,hw:0
-a:1 -erc:1,2 -ea:100 -epp:50 -efl:20000 -efh:4
-a:1.1 -erc:1,2 -ea:187 -epp:50 -efl:20000 -efh:4 -ete:38,10,99

I get...

- [ Controller/Processing started ]
--------------------------------------------
ecasound ('h' for help)> (eca-engine) Using realtime-scheduling
(SCHED_FIFO:50).

... but nothing happens... Then I do EIAM command "q" and it hangs
(pressing ENTER just reveals new blank lines in the console). Then I
finally do "CONTROL C" and after a few seconds I get..

- [ Controller/Processing stopped (cond) ]
-------------------------------------

The funny thing is that if I take the (above) ECS file, but add a
completly seperate input to it...

-a:1,1.1 -f:16,1,48000 -i:Guitar.wav,
-a:2 -f:16,1,48000 -i:Vocal.wav,
-a:1,1.1,2 -f:16,2,48000 -o:alsa,hw:0
-a:1 -erc:1,2 -ea:74 -epp:50 -efl:20000 -efh:4
-a:1.1 -erc:1,2 -ea:211 -epp:50 -efl:20000 -efh:4 -ete:38,10,99
-a:2 -erc:1,2 -ea:160 -epp:50 -efl:20000 -efh:4

... and let it run till the longest file stops playing, then do EIAM
command "setpos 0" then "t"... it runs from the beginning perfectly
without a problem.

Then I wanted to see what happened if I added a second chain to the new
input and then did "setpos 0" then "t"...

-a:1,1.1 -f:16,1,48000 -i:Guitar.wav,
-a:2,2.1 -f:16,1,48000 -i:Vocal.wav,
-a:1,1.1,2,2.1 -f:16,2,48000 -o:alsa,hw:0
-a:1 -erc:1,2 -ea:74 -epp:50 -efl:20000 -efh:4
-a:1.1 -erc:1,2 -ea:211 -epp:50 -efl:20000 -efh:4 -ete:38,10,99
-a:2 -erc:1,2 -ea:160 -epp:50 -efl:20000 -efh:4
-a:2.1 -erc:1,2 -ea:211 -epp:50 -efl:20000 -efh:4 -ete:38,10,99

Everything ran fine. There only seems to be a problem if there's only
one input with several chains.
