[AL] file problems

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

I just wrote my map editor and to save a map
which is a 400x400 array of 3 bytes structs, 
I do this :

void save(MAP map[][MAP_SIZE], char *file)
{
 PACKFILE *to_save;

 strcpy(file, "c:/dave/prog/projects/djgpp/zoltrax/src/");

 if (file_select("save as :", file, "dat"))
 {
  if((to_save = pack_fopen(file, "w")))
  {   
   pack_fwrite(map, sizeof(MAP)*MAP_SIZE*MAP_SIZE, to_save);
   pack_fclose(to_save);
  }
  else alert("error saving file", "", "", "ok", NULL, KEY_ENTER, 0);
 }
}     

but it crashes every time (I get allegro shut down)
I tried with FILE, fopen, fwrite and fclose but
I get the same result.

Here's what I get :

Shutting down Allegro
Exiting due to signal SIGSEGV

Call frame traceback EIPs:
  0x0003a298

just as I save, the strange thing is that there is
a file written on my drive (the size seems ok).

any help would be appreciated
thanx
Dave

Ummm, I just tested that and on my system the slider goes up to 47.50 Mb
(out of 96Mb RAM).

Now that would be good!  We could make sure that at least on SB Live the
MIDI music sounds like it should (by uploading the right soundfont.).

I d/l-ed that 12Mb soundfont Tom mentioned and it's quite an improvment
over the 8Mb that came w/ the card.
