I have hit this bug with a recent commit to druntime that changes the
implementation of AssociativeArray.keys:

import std.stdio;

void main()
{
    string[] files;
    files ~= "1";
    files ~= "2";

    byte[string] cache;
    cache["3"] = 1;
    cache["4"] = 1;

    files ~= cache.keys;
    writeln(files);
}

when compiled with -inline, it prints

["1", "2", "\x01\x00"]

This seems to be caused by inout(T[]) not being appendable to T[]. Instead it
is appended as a single element (_d_arrayappendcT is called, see
CatAssignExp::toElem).

In case of AssociativeArray.keys, there also seems to be a problem that
inlining seems to ignore implicite conversion on the return type by the inlined
function.
