Backtrace results say that it hopped through all of the eca code okay. At
step #6 it says "0x804c59b in main()". At step 7, the program freezes... bt
says "#7 0x403bf9cb in __libc_start_main () at
../sysdeps/generic/libc-start.c:122". Does this mean there's a problem with
libc?
Here's an attatched output of ldd ecasound-debug...
Thanks.
