Full console output
A toy sample program I used to study the CUDA backend transformations does not compile with the flag -doexpar, sorry for not reporting this earlier. The compiler exists with the following message:
$ sac2c -target MBpro_cuda mt_cuda.sac -doexpar -dopfd
...
** 20: Preparing C code generation ...
  **** CUDA Prepare kernel generation ...
  **** Marking memval identifiers ...
  **** CUDA Adjust return ids of single threaded kernel ...
cuda/adjust_stknl_rets.c:486 Assertion "!TUisScalar( AVIS_TYPE( ID_AVIS( ret_id)))" failed!
Scalar found in N_return!
The code for mt_cuda.sac:
inline
int add( int a, int b) {
  return( _add_SxS_( a, b));
}
int main( ) 
{
 x = 1;
 foo = with {
                ([1,1] <= iv=[i,j] < [40960,4096]) {
                  res = 20;
                }:res;
              }:genarray([40960, 20000], 0); 
 y = add(x,_sel_VxA_([1,20],foo));
 foo = with {
                ([0,10] <= iv=[i,j] < [40960,4000]) {
                  res = 0;
                }:res;
              }:modarray(foo); 
  z= add(y,_sel_VxA_([1,2],foo));
  w = with {([0,0] <= iv < [40960,20000]): _sel_VxA_(iv,foo);}: fold( add, 0);
  return( add(z,w));
}
I'm attaching the full console output of sac2c too. I'm using latest version from svn (rev. 17876).
