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.
