Consider running it with valgrind. It will automatically detect some
program errors. IIRC leaked fhs are only listed at termination so run it
for some time and then exit it so you get a nice report. use at minimum
-v. See --help.

Please note that kh isn't offically supported by the xiph foundation. So
