The program below crashes with "Bus error" when trying to compile from the
command line on Mac OS X 10.6.3. I know this was not crashing the compiler a
few versions ago (some time early january 2010).

---
import std.conv;

struct SomeStruct { }

void main() {
    auto s = to!SomeStruct("hello");
}

It is a real problem for me that it crashes the compiler since I'm using a
__traits(compile, ...) with something similar for conditional compilation, and
this does not work anymore.

---
import std.conv;

struct SomeStruct { }

void main() {
    static if (__traits(compiles, to!SomeStruct("hello"))) {
        auto s = to!SomeStruct("hello");
    }
}
