Also, this doesn't happen only for array literals.  Here, I .dup the literals
to make sure they're allocated like "normal" arrays and it still happens.

import std.stdio;

void main() {
    uint[] foo = [1U,2,3,4,5].dup;
    ubyte[] bar = [cast(ubyte) 1,2,3,4].dup;
    foo ~= bar;
    writeln(foo);  // 1 2 3 4 5 67305985
    foo.length = 5;
    ulong[] baz = [1UL,2,3,4].dup;
    foo ~= baz;
    writeln(foo);  // 1 2 3 4 5 1 0 2 0 3 0 4 0
}

Could this be a regression?
