Okay i'm working on a game with Allegro, and it works fine under a windows 95
dos box, however whenever i go into dos mode (and try to run cwsdpmi.exe), when
I run my program it exits giving me a SIGSEGV, I ran symify, and below is the
results.  Can anyone tell me what this stuff means?  I will post the source
code to my program later if someone needs to look at it to help.  I'm not doing
anything out of the ordinary for djgpp or allegro, so i couldn't understand
what could be wrong.
Also I noticed similar problems happening with the last couple of allegro
examples programs too.  They will basically work under a win95 dos box but not
under dos mode itself.  Note i'm running allegro version 3.11 (and i've just
reinstalled it)  So does anyone have any ideas?                             
Thanks -Keith W. II
