#14 sctl-0.2.3 load/write hang

[Anonymous]

I'm getting a load/write hang while using sctl-0.2.3.
I've been able to repeat this bug over and over.

dump.null file is a file with null conv freqs (ie. 0 F
F N F 0)
Hang at "read(4,"

If I use a file loaded with conv frequencies, it will
sometimes fully upload itself (sometimes after a couple
of tries... but it finally goes). But repeating to
upload the same file creates a hang such as this
"dump.null" file loaded with null frequencies.

$ strace ./sctl load e dump.null
