Crash on exit for underflow example

[thenewandy]

Running the overflow test on ubuntu 24.10, I get a crash on exit:

(gdb) r
Starting program: /home/andy/scratch/libsoundio/foo/underflow 
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
You should hear a sine wave for 3 seconds, then some period of silence or glitches,
then you should see at least one buffer underflow message, then hear a sine
wave for 3 seconds, then the program should exit successfully.
WASAPI does not report buffer underflows.
