Could you try replacing your client code with something based on the following?

#include <pv/pvData.h>
#include <pva/client.h>
namespace pvd = epics::pvData;
struct Example {
   pvac::ClientProvider ctxt;
   pvac::ClientChannel chan;

   Example()
       :ctxt("pva")
       ,chan(ctxt.connect("CRYVISIL:STM:FASTSCAN:IMAGE_CHUNK"))
   {}

   void put(long val) {
       pvd::shared_vector<double> X, Y, Z, T;

       for(long i=0; i<100; i++)
           X.push_back(i);

       for(long i=0; i<100; i++)
           Y.push_back(i+1);

       for(long i=0; i<100; i++)
           Z.push_back(i+2);

       for(long i=0; i<100; i++)
           T.push_back(i+3);

       chan.put()
               .set("value.column0", pvd::freeze(X))
               .set("value.column1", pvd::freeze(Y))
               .set("value.column2", pvd::freeze(Z))
               .set("value.column3", pvd::freeze(T))
               .set("counter", val)
               .exec();

       std::cout<<chan.get();
   }    
};
