Segfault on memory deallocation #12

Closed bbrelje closed 4 years ago

bbrelje commented 5 years ago

Type of issue

What types of issue is it?

Description

Commit 342d98fe0f57cc20e3c25f2f48efdb84dd61db40 removed the common_to_dxs VecScatterCreate function from initializeWarping.F90. However, the VecScatterDestroy destructor on line 49 of releaseMemory.F90 was not removed. PETSc therefore tries to destroy an uninitialized VecScatter object and segfaults.

Steps to reproduce issue

  1. Compile idwarp using GCC 7, PETSc 3.11, and Sandy's fork of idwarp
  2. cd idwarp/python/reg_tests
  3. python solve_script.py test2
  4. Redo with debug flags turned on and using Valgrind if desired to localize the error

Current behavior

Segfaults

Expected behavior

No segfault

Code version (if relevant)

Python version: Miniconda 3.7

External dependencies:Petsc 3.11

Internal packages: idwarp latest Sandy fork
