Hello. I'm having a problem with vectors in DJGPP (and Allegro). I'm making
a vertical shooter, and just for fun, I've been pumping up how many
enemies/bullets are on screen at once. All objects are stored in vectors of
pointers to them. If the vectors get too large, the program crashes. I don't
know if it helps, but I've included results of symify; the reason I'm asking
this here is the presence of the dj_movedata error; this is a DJGPP thing,
correct (same with new2.cc)? Also, if someone could tell me if there's
anything further I can do with this mess of numbers (after symify) that
might help too...

Thank you for any help.


Chris
