Apparently rsync calls mmap to create an anonymous mapping. mmap
memory areas are allocated top down. Also top-down allocated are
the OS areas which correspond to the PEB and the TEBs. The above
memory collision is probably one where the mmap area collides with
a TEB or PEB. I'm testing on W* as well and I'm running a W2012
server all the time since last Friday, but I didn't observe this
problem yet. I also can't reproduce it with some arbitrary rsync -a
command. What rsync command are you using?
