Comment (by rhaas):

 Ok, got a test case:

 {{{

 index a2725d3..ffbf9b2 100644
 --- a/Vectors/src/vectors.cc
 +++ b/Vectors/src/vectors.cc
 @@ -7,5 +7,8 @@
  extern "C" int Vectors_Startup(void) {
    CCTK_VInfo(CCTK_THORNSTRING, "Using vector size %d for architecture
 %s",
               CCTK_REAL_VEC_SIZE, vec_architecture);
 +
 +  CCTK_REAL myscal = 42.;
 +  vectype<CCTK_REAL> myvec(myscal);
    return 0;
  }
 }}}
 which fails with:

 I attach a tarball of the modified Vectors thorn as well as config-info.
