If you can figure out why that happens, I'd really appreciate a simple
testcase.  Please compare the above with the strace output generated by
mmap(), probably you will find a discrepancy like the address in the
above strace output is not inside of a mapped block.  It's also a big
difference if the mmap is mapped anonymously or to a file since the mmap()
code behaves pretty different.

Another way would be to remove MAP_PRIVATE from the mmap() call and try
again.  MAP_PRIVATE is somewhat problematic on Windows hosts, unfortunately.
