I hate it when that happens.  NTVDM bugs.  The more you can tell us
about where it dies, and the state when it dies (size of sbrk request,
current sbrk point, etc) are helpful.

In the same place, or earlier?  It's not clear to me if the refresh
is making this better or worse; and if the unixy sbrk() flag  makes this
better or worse in either case.  Oh wait, EMACS does that dump thing,
so unixy sbrk() will really be a requirement unless someone stops that
insanity at least for initial dumps. :-)  Since it has it's own malloc()
it just might require unixy sbrk() anyway.  So nothing would surprise me.

No newer sbrk().  What's in the refresh was actually mostly sitting on
my hard drive from a long time ago, waiting for the time to merge it
back into the main branch and test it.  I really haven't messed with
sbrk() much since last July or so.

Someplace on a backup CD I have an sbrk() test program, but I may have
to just re-write it.  I'd like to try the sbrk() flags on Win2K and
see if it's just badly behaved, or if there is something else emacs
does which irritates NTVDM.
