std::os::MemoryMap::new() fails on Windows

[jamesluke]

Code:

extern crate native;
extern crate rustrt;
use rustrt::rtio::{Open,Read};
fn main() {
    let file = native::io::file::open(&"test.txt".to_c_str(), Open, Read)
        .ok().unwrap();
    let map_options = [std::os::MapReadable, std::os::MapFd(file.fd())];
    std::os::MemoryMap::new(2048, map_options).unwrap();
}

Error: task '

Known issue #13259

[alexcrichton]

Yes, I just ran into this as well, and it looks like this is a dupe of #13259. @jamesluke, can you confirm the workaround in that issue works by adding this early on in your code?

unsafe { ::std::rt::stack::record_sp_limit(0); }

[jamesluke]

Just tried this again with the latest nightly (would give commit, but for some reason 'rustc --version verbose' isn't giving me one), it now works even without the record_sp_limit(0) workaround you suggested.

Thanks for investigating @jamesluke! I think I'll just chalk this up to the mysteriousness of #13259 in that case!
