In "emulated" mode printf always prints zero for any number

What steps will reproduce the problem?
1. In file "configure.ocelot" set device to "emulated"
2. Compile and run the following hello world program

#include <cuda.h>
#include <stdio.h>

__global__
void
helloKernel(){
  if(threadIdx.x & 1 > 0){ //odd thread
    printf("Hello world, from odd thread %d\n", threadIdx.x);
  }else{
    printf("Hello world, from even thread %d\n", threadIdx.x);
  }
}

int
main(int argc, char* argv[]){
  dim3 grid(1,1);
  dim3 block(20,1);
  helloKernel<<<grid, block>>>();
  cudaDeviceReset(); //needed to flush printf cuda buffer
  return 0;
}

3. The printf always prints "0" for every number (I also tried to print 
constants and literals... same result) 

4. If I remove "emulated" from the device field and leave only "llvm" then the 
output is as expected

What version of the product are you using? On what operating system?
gpuocelot 2.1 build 1985
Debian Linux wheezy
