Attached code compiles bug segfaults on both:
Windows_NT luka8088-PC 6.1 7601+Service_Pack_1
Linux atom 2.6.32-5-686 #1 SMP Mon Oct 3 04:15:24 UTC 2011 i686 GNU/Linux

I have no idea way :$

Make sure it is compiled as -unittest, correct output should be: S1([[1]])

The order of how you compile the files matters:

Reduced

------ m1.d -----
module m1;

import std.stdio;
import callback;

struct S1 {
  int[][] a1 = [[1]];
}

@safe auto f1 (S1 r, bool o, dchar a, dchar b) {
  return r;
}

@safe auto f2 (T1, T2) (S1 r, T1 g, T2 h) {
  alias cpt = bind!(f1, r);
  return f3!(cpt!(bool, dchar, dchar))(g, h);
}

@safe auto f3 (alias l = (a, b, c) => 0, T1, T2) (T1 d, T2 e) {
  return l(true, 'a', 'b');
}

void main() {
  S1 s1;
  auto z = bind!(f2, s1)("", "");
  writeln(z);
}
----callback.d ----

module callback;

template bind (alias f, bindValues...) {
  auto bind (types...) (types values) {
    return f(bindValues, values);
  }
}
------------------

If compilation starts with 'callback' the program crashes, can confirm in 2.063 git head.

Further reduced:

-----callback.d-----
module callback;

auto bind(alias f, bindValues...)()
{
   auto bind(types...) (types values)
   {
      return f(bindValues, values);
   }
   return bind();
}
----m1.d--------
import callback;

extern(C) int printf(const char*, ...);

struct S1 {
   int a1 = 1;
}

@safe auto f1 (S1 r) {
  return r;
}

@safe auto f2()(S1 r) {
  return bind!(f1, r);
}

void main() {
  S1 s1;
  auto z = bind!(f2, s1)();
  printf("%d\n", z.a1);
}
-------------------------
Compile with callback as first argument, program prints garbage.

The problem appears in:
Dump of assembler code for function
_D2m14mainFZv43__T4bindS62m12f2S23_D2m14mainFZv2s1S2m12S1Z4bindMFNfZS2m12S19__T4bindZ4bindMFNfZS2m12S1:

   0x000000000041a1bd <+1>:    mov    %rsp,%rbp
   0x000000000041a1c0 <+4>:    sub    $0x10,%rsp

   0x000000000041a1cf <+19>:    retq
End of assembler dump.

If m1.d is compiled first, instruction is mov -0x8 (%rdi),%edi which is correct
(function got RBP as argument, so it should read 8 bytes below).

Moreover, there is ice here: if you transform f2() from function template to
template (again, you need to compile callback first), you get:

m1.d(13): Error: function m1.f2 compiler error, parameter 'r', bugzilla 2962?
dmd: glue.c:817: virtual void FuncDeclaration::toObjFile(int): Assertion `0'
failed.
Aborted

After reading issue 2962 I raise status to critical because this bug seems to raise old nasty bug marked as fixed and critical.
