           Summary: Associative array assignment with dstring keys breaks
                    lookup
           Product: D
           Version: D2
          Platform: x86_64
        OS/Version: Mac OS X
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: nobody@puremagic.com

void main () {
    int[dstring] foo;

    foo = [
        "hello"d : 5
    ];

    assert("hello"d in foo);
}

This assertion fails on dmd 2.047 on OS X. Using foo["hello"d] = 5; or changing the key type to string works.

Forgot to add that the keys and values are still iterable with foreach() - it's
just lookup by hash (index or "in" syntax) that fails.

I hit this bug when I wrote a Japanese language morphological analysis library (http://bitbucket.org/repeatedly/scrap/src/tip/tinysegmenter.d).

I voted.

Mass migration of bugs marked as x86-64 to just x86.  The platform run on isn't what's relevant, it's if the app is a 32 or 64 bit app.

Most likely a druntime string comparison issue.

This bug appears to be the same as bug 7512, which has been fixed in git. Please verify.
