Okay, I narrowed it down as much as I could to this little test.

bug.d:
[code]
module bug;

import std.stdio;

class Bug
{
   char[12] str = "";
   uint t = 1;
}

class NoBug
{
   uint t = 1;
   char[12] str = "";
}

class NoBug2
{
   char[12] str;
   uint t = 1;
}

void main()
{
   auto b = new Bug;
   auto n = new NoBug;
   auto n2 = new NoBug2;

   writefln("bug %d", b.t);
   writefln("nobug %d", n.t);
   writefln("nobug2 %d", n2.t);
}
[/code]

$dmd -w bug.d
gcc bug.o -o bug -m32 -lphobos -lpthread -lm

$./bug.d
bug 0
nobug 1
nobug2 1
