odd error with read_bitmap()

This is really odd.
In my program I call read_bitmap (s=read_bitmap("myfile.bmp") and check
the length of the sequence. It is 2. That is correct. I then display the
bitmap and it displays ok. The whole program runs fine. But when I
return to the editor, I get a type check error that says s=1. (s is
declared as a sequence) If I rerun the program I get this windows error:

subsystem MS_DOS 16 bits
in cmd.exe
O cpu ntvdm found the following illegal instruction
CS:d402  IP:0000	OP:ff 3f ff 1f ff
select Quit or Ignore

Then dos aborts back to windows.

Odd, yes?

Why does it run once but not twice? Taking the offending subroutine to a
little test.ex file runs fine every time, so maybe it is some leaky
memory thing? If that is the case, is there something I can do about it?
Why does my program run but give me a type check error anyways?  It
doesn't make any difference if I have with or without type_check.
