I have compiled the program and it runs without any problems on my
machine. The stack backtrace seen above is very strange. At line 104
of display.c there's a call to the 'fgets' function which DOES NOT
call any function that might invoke 'free()'. Are you sure you're not
mixing libraries from DJGPP v2.0 and 2.01? Check whether ALL of them
are compiled with one and the same version of DJGPP. What version of
PDCURSES do you use?

Both of them were displayed properly on my machine.

So I talked about conscience and I talked about pain,
And he looked out of window and it started to rain
I thought maybe I've already gone crazy...
