Here is the story.  I have used allegro a little in the past and now I
am trying to get the feel for it again.  While putting together a little
mouse test program (to teach myself) I ran into a snag early on.  Before
I even got to the mouse part I wanted to put up a background.  So
reverse engineering from example code this is what I have.  (FYI the
back.bmp is 500x400 256co)  When I run it I get a general fault, a bunch
of hex stuff and 2 call fram traceback eip's   0x00003870 and 0x0002c2a2

I know this isn't THAT difficult I just wonder what I am missing, any
help would be greatly appreciated.

--------------------------CODE BELOW--------as if you couldn't guess
#include <stdlib.h>
#include <stdio.h>
#include <allegro.h>
/* This is the first mouse program...hopefully load a bitmap on the
screen and when certain parts are toggled it will do different things*/
int main()
{
   BITMAP *back;
   PALLETE pal;
    clear(back);
   allegro_init();
   install_keyboard();
   install_timer();
   set_gfx_mode(GFX_VGA, 320, 240, 0, 0);
   back=load_bitmap("back.bmp",pal);
   if (!back) {
     printf("Error reading bitmap file ");
    return 1;
   }
   set_pallete(pal);
   blit(back, screen, 0, 0,(SCREEN_W-back->w)/2,
       (SCREEN_H-back->h)/2, back->w, back->h);
   destroy_bitmap(back);
   readkey();
   return 0;
}
