gcc quite correctly complains about this:
In file included from ../../include/scrnintstr.h:51:0,
from rootlessValTree.c:98:
In function 'RegionUninit.isra.1',
inlined from 'RegionEmpty' at ../../include/regionstr.h:194:5,
inlined from 'RootlessMiValidateTree' at rootlessValTree.c:490:9:
../../include/regionstr.h:166:9: warning: attempt to free a non-heap object 'RegionBrokenData' [-Wfree-nonheap-object]
free((_pReg)->data);
So that'd crash if you ever got there. RegionNull will do almost the
same thing only without the free(), so let's do that instead; it might
still not be an entirely sane way to recover, but it at least won't
crash.
