Comment(by jdemeyer):
I think I just had a small break-through:
The gp command now has the so-called "breakloop" on by default. This
means the following: if Sage executes a command through the gp interface
which gives errors, the following will be displayed in the pseudo-tty
(invisible to the Sage user):
{{{
? 1/0
*** at top-level: 1/0
*** ^--
*** _/_: division by zero
*** Break loop: type 'break' to go back to GP
break>
}}}
Now gp just waits for user input. Since that input will never come, it
just sits there forever.
I have a temporary workaround for this:
in the directory SAGE_ROOT/local/bin, move "gp" to "gp-real". Then create
the following shell script called "gp":
{{{
!/bin/bash
mkdir -p $HOME/sage_debug
export HOME=$HOME/sage_debug
echo "breakloop = 0" >$HOME/.gprc
# Remove --fast option
exec $SAGE_ROOT/local/bin/gp-real --emacs --quiet --stacksize 100000000
}}}
This changes $HOME and makes a .gprc file in it which disables the break
loop. It then runs gp without --fast, so that the .gprc file is read.
