The following code reproduces this problem for me
(The CMakeLists.txt simply calls the DEAL_II_INVOKE_AUTOPILOT() macro):
#include <iostream>
#include <deal.II/base/mpi.h>
intmain (int argc, char *argv[]) {
dealii::Utilities::MPI::MPI_InitFinalize mpi_init (argc, argv);
std::cout << "Program runs normally." << std::endl;
return 0;
}
Initially I suspected that the mpi_init object might be optimized away by the
compiler. But adding volatile to its
declaration does not fix this. Now I still do not know what is causing the
problem. Any help or suggestion is appreciated.
Does this also happens with just a single processor? If you run this in a
debugger, can you get a backtrace that shows where the problem happens?
Best
