           Summary: TypeInfo.getHash should not be trusted
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: druntime

When getHash is overridden, it may try to dereference the void pointer, so it's
not safe if the pointer is to the wrong type.

import std.string;

static int x = 35873;

 safe
void main() {
    typeid(string).getHash(&x);
}

An example program which segfaults within a  safe method
