www.sakla.net/regression.q shows the latest version. With this syntax

pspp calls run_regression(...) with no trouble. This function exits,
then cmd_regression() exits normally. Then pspp is in parse_script ()
at main.c:101, and handle_error(execute_command()) never returns. This
problem never occurs with old_regression.q. Does anyone know what's
happening here?
Our trusty friend valgrind shows:

So I deleted line regression.q and everything ran fine. I didn't see
any output, but I guess you haven't implemented that bit yet.
And does regress.q have the right look for a new
procedure? (Aside from the fact that it doesn't work yet.)
It looks good to me.
