Is this NULL pointer bug in vim 6 DOS-only, or does it affect vim in all OSes?
vim 6 I have, 32-bit version, seems quite stable as long as I only handle one
file at a time.  I am not interested in 16-bit version because I need to handle
files that don't fit in low DOS memory.  Text editors that only handle up to
maybe 370 KB are all too easy to come by for DOS.

In DR-DOS, unlike MS-DOS, you are not supposed to use HIMEM.SYS at all when you
use EMM386.EXE.
