Subject: [ecasound] segfaults with CVS ecasound when using LADSPA plugins
From: Tim Westbrook (iondiode_AT_yahoo.com)

Hello,
Not sure if I am supposed to report problems with CVS versions but
this seemed sufficiently wierd.
While playing around with the text-mode ecasound I started
seeing segfaults when processing files ( -i:file -o:newfile ). But
only when I added -el effects. This does not happen with -pn effects
or when the output is a soundcard. ( -o:alsa,sblive ). The oddest
part is that that the file is created fine, ecasound seems to crash
during the cleanup process
The command I used to see this problem
ecasound -d:0 -i:/data/samples/x.wav \
-o:/data/samples/ecatest.wav \
-el:identity_audio
I have included below , some relevant output of ecasound and gdb. As
$Subject states I am using CVS version checked out last night.
I was also seeing segfaults with when using LADSPA plugins with my
sound card as the output , but these went away after changing my
-b(uffer-size) to 4096. So these are probably issues with my crappy
soundcard :-(
