PROBLEM: gMFSK v0.5 locks up.

Hi,

Now that I've got gmfsk to compile, I run into another problem.

Until now I didn't get it to produce any sound yet. (sound works on that 
system. Other applications can use the sound card)

There are 2 ways that I can make gmfsk lock up.

1. click the "Abort transmission immediately" button.
2. click the "Mode" pull-down menu and try to select another mode.

There are no messages in /var/log/syslog and /var/log/messages
I'm using fftw-2.1.5, kernel 2.4.21 glibc-2.3.1 and all were compiled 
with gcc-3.2.3.

Any ideas? Can somebody point me in the right direction?
