Good idea (modulo /sdterr/stderr/), I have removed the included XRef.h
and added this warning for poppler builds, and for xpdf build do as
normal. Thanks.

The pdftosrc.cc now looks like:
...
            else {              // e->offset is the object number of the object stream
#ifdef POPPLER_VERSION
                fprintf(stderr, "warning: this version of pdftosrc doesn't support object stream (use pdftosrc from TeX Live if you need it)\n");
#else
                // e->gen is the local index inside that object stream
                //int objStrOffset = xref->getEntry(e->offset)->offset;
                Object tmpObj;

                xref->fetch(i, e->gen, &tmpObj);        // to ensure xref->objStr is set
                ObjectStream *objStr = xref->getObjStr();
                assert(objStr != NULL);
                int *localOffsets = objStr->getOffsets();
                assert(localOffsets != NULL);
//                 fprintf(outfile, "%0.10lu %i n\n",
//                         (long unsigned) (objStrOffset), e->gen);
                fprintf(outfile, "%.10lu 00000 n\n",
                        (long unsigned) (objStr->getFirstOffset() +
                                         localOffsets[e->gen]));
//                         (long unsigned) (objStrOffset +
//                         objStr->getStart() + localOffsets[e->gen]));
                tmpObj.free();
#endif
            }
...


Best wishes
