My tree was up to date, so I compiled a debug binary and ran it into gdb.
I won't include ecasound's output because it's basically the same that I've
already posted.
the command was: "ecasound_debug -d:255 -i:test.wav -o:null"
(I dropped the -ev thing since it's obviously not the problem.)

One thing that's weird is that gdb starts the program, I get the nice
little header with copyright info and all, then "Session created", but
after that, gdb crunches for about five minutes before ecasound
continues to output to the screen. It wasn't this way last time I ran
ecasound in gdb, a couple of months ago...

Yes, sometimes debugging info can get messy...
