gp version 2.0 under emacs

[Kevin Buzzard <K.M.Buzzard@dpmms.cam.ac.uk>]

Hi pari-users. I've compiled gp version 2.0 alpha for RedHat Linux on an i586
and it works just fine by itself, but I can't get it to run under emacs.
I've manged to compile pari.el, and M-x gpman
does work, but M-x gp just leads me into an infinite loop with
the message "Waiting for gp output ..." at the bottom line of my
emacs window, and the buffer is still *scratch*. The problem occurs
with both the static and dynamic compilations. Could it be a prompt
problem? I have *not* changed the default prompt in my .gprc; the only
thing my .gprc does is bumps up parisize to 10 000 000. I have no GPRC set.
My prompt is "? " if I run gp from a shell.

Anyone have any ideas/experienced similar problems?

(at this point we just sit and wait forever; I can type C-g and break out
of the loop, and I get a corrupted gp session in my emacs window, whose

Type ? for help.

   realprecision = 28 significant digits
   seriesprecision = 16 significant terms
   format = g0.28

parisize = 10000000, primelimit = 500000, buffersize = 200000
[?1h=? 

It is possible to use gp now...but I have to press the delete key 6 times
before I enter each command, to eat up the gunk in the prompt.)
