A user who experience this issue for the first time and had Emacs crash,
would have no indication whatsoever what hit them, i.e. they wouldn't
know how to
react. Thus my suggestion for checking for the NULL pointer in
unload comp, so that they at least see the error message about
the .eln files being inconsistent and research ways to go around it.
And I can see two ways going forward:
1. Take a step back and switch off native compilation (but how to do this
other than recompiling Emacs?)
2. Stil use native compilation but change the destination .eln directory
to a safer path, so that they can still rip the benefit. I'd expect the AV
only have a limited set of dirs preventing GetProcAddress of
operating, otherwise nothing would work.
Thanks
