Segmentation faults in OpenMP implementation #1

Open mickyaero opened 7 years ago

mickyaero commented 7 years ago

The value of currentStep_ is being updated just once. When the test_ksolve.py is run, it gives segmentation faults and sometimes correct answer(repeated answers). The branch is ksolve_openmp

Seems like the seg-fault in in moose.Table. Sometimes it runs. This kind of bugs are hard to debug.

My guess is that moose.Table needs to check that object exists before reading the value. Some thread might exist before moose.Table reads them at the end; and all a Table left with an object which may be garbage collected (seg-fault); if not then execution is successfull. Just a guess.

Reproducible with clang++ compiler and python3 as well.
