Segmentation fault in gtest_filter="SUMMA*" with 8 processes

Open tuxamito opened this issue 8 years ago • 1 comments

On current development branch (tag dash-0.2.0-2506-g47b12a9)

System: Linux Mint 18.1 (based on Ubuntu LTS 16.04) 4+HT Skylake (i7-6700K) mpic++ gcc version 5.4.1 20160904 mpirun (Open MPI) 1.10.2

There is a segmentation fault when executing the dash-test-mpi application as follows: mpirun -n 8 dash-test-mpi --gtest_filter="SUMMA*" while with 4 processes it ends apparently correctly.

I attach the output with valgrind for -n4 and -n8 for this command: mpirun -n x valgrind ./dash-test-mpi --gtest_filter="SUMMA*"

Good catch, thank you. I have an idea what might have caused this, will report back here.
