Interesting, thanks.  I noticed something similar when trying to 
call malloc in a pure function...

std.internal.memory:
```d
extern (C) @nogc nothrow pure private
{
     pragma(mangle, "malloc") void* fakePureMalloc(size_t) @safe;
     pragma(mangle, "calloc") void* fakePureCalloc(size_t nmemb, 
size_t size) @safe;
     pragma(mangle, "realloc") void* fakePureRealloc(return scope 
void* ptr, size_t size) @system;
}
```
