<div dir="ltr">Hi guys,<div><br></div><div>I'm having a really weird issue here! My code seg faults for certain problem size and after using gdb I have been able to pinpoint the problem to a VecGetArray call. Here's a series of things I have tried so far</div>
<div><br></div><div>1) -on_error_attach_debugger -----> unsuccessful; does not launch debugger </div><div>2) -start_in_debugger -------> unsuccessful; does not start debugger</div><div>3) attaching debugger myself -----> code runs in debugger and seg faults when calling VecGetArray</div>
<div>4) using ierr=VecGetArray;CHKERRQ(ierr) ------> PETSc does not produce error messages; the code simply seg faults and terminates</div><div>5) checking the values of ierr inside the debugger ---------> They are all 0 up untill the code terminates; I think this means petsc does not generate error?</div>
<div>6) checking for memory leak with valgrind -----------> All I get are leaks from OpenMPI and PetscInitialize and PetscFinalize; I think these are just routine and safe?</div><div><br></div><div>What else can I try to find the problem? Any recommendation is really appreciated!</div>
<div><br></div><div>Thanks,</div><div>Mohammad</div></div>
