Be sure, you compiled it with "-g" for debugging.

Use gdb. Somehow like:

# gdb `which audacity`
(gdb) run

If it segfaults type in "bt" to get a more verbose error message. There
might appear other signals like "SIGUSR1", just "continue" or ignore them
with e.g. "ha nostop noprint pass SIGUSR1". Be sure everything is
up-to-date and kernel is in sync with userland. At first, try "make
update" in audio/audacity.
