Hi,
this issue has been possibly solved in upstream release 2.4.5. Version
2.4.6.1 is already in testing/stable so the bug should be fixed there.

Segfault on exit/interrupt by TERM signal (kill or "Ctrl-C"); hang on small
buffer value in args.
Firstly about hangs, it's short. When I tried launch ecasound with small
buffer option, it hung, and so was killed with -9. The command line follows:
ecasound -b:128 -i ~/music/somefile.mp3 -o /dev/dsp
I don't know should it be named problem or bug at all, but nevertheless
it exists. Quite unsure if I had to create separate report mail, so it is
included here.
Secondly, about segfaults on interrupt. (Note: may be it's a problem
of plugins?)
I have met this problem trying examples from
http://www.eca.cx/ecasound/Documentation/examples.html, these command lines:
ecasound -i null -o /dev/dsp -el:sine_fcac,440,1
ecasound -i:null -o:/dev/dsp -pn:metronome,120
Segfault happens not always, but usually.
Terminal output for "kamerton" run and two (normal and segfaulted) for
"metronome" runs follow. Same results for "Ctrl-C" stops and kill -15.
The most of other example command lines from that address didn't cause
segfaults
on terminate.
$ ecasound -i null -o /dev/dsp -el:sine_fcac,440,1
