I am stuck on this error... it doesn't really concern me, since I have now
been trying to recreate the error once again (for half the day that is) and
I wasn't able to. Funny is, I have not even touched the source code but
recompiled and relinked it. It still works all fine... I made a change a few
minutes ago to fill an array with zeros before working with it, so it
doesn't hold garbage. My program was failing when working on that array...
but maybe that's was my problem. The array would normally be a huge or far
array, since it breaks the 65k limit I am used to... but since it compiled
without any errors I thought it may be okay under DJGPP. Could this cause an
error like I mentioned?
