I have been making a funky graphics engine which requires the use of
recursive calls.  I may be a little rusty from my old comp sci classes, and
am getting some odd errors.  The basic deal is this:  I send DrawSector a
pointer to the sector to draw, and it draws until it finds a wall that
points to a new sector.  It then calls itself passing the pointer to the
new sector.  One sector works quite well, and when I link two together, it
still works.  So then I rotate the sectors a bit and all of a sudden, the
first recursive call handles a few of the elements of the sector properly
and suddenly goes into fits trying to access random memory.  Needless to
say this crashes...  I have a feeling it is the cause of a stack overflow
of some sort, but I am not sure.  If you have any ideas on how to correct
this they would be greatly appreciated, if not, do you know of a compiler
switch to increase the stack size for functions from within DJGPP,
specifically RHIDE?  Any help any of you could offer would be greatly
appreciated.
