Just for the records,
I have been trying to track this "the dumb way" (putting messages here and
there) and seems that the problem is in a call to gp_get_string called
from read_line called from com_line (all in command.c).
I had no time to go further and do not know when I will have it. I am
attaching a diff with a minimal fprintf set around the problem.
Hope this helps,
