          Issue ID: 20878
           Summary: .stringof inconsistent between 32-bit and 64-bit Linux
           Product: D
           Version: D2
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: snarwin+bugzilla at gmail.com

The following example compiles successfully on 64-bit Linux, but fails on
32-bit Linux:

---
module testInference;

import core.demangle: demangle;

void foo8504()() {}

auto toDelegate8504a(F)(auto ref F fp) { return fp; }

extern(C) void testC8504() {}

void test8504()
{
    // commenting out the following line makes the test pass on 32-bit linux
    static assert(demangle(foo8504!().mangleof) == "pure nothrow @nogc @safe
void testInference.foo8504!().foo8504()");

    auto fp1 = toDelegate8504a(&testC8504);
    static assert(typeof(fp1).stringof == "extern (C) void function()");
}
---

Error message on 32-bit Linux:
---
testInference.d(19): Error: static assert:  `"extern (C) void function()
@system" == "extern (C) void function()"` is false
---

Possibly related to issue 3796.
