Created by: jhidding

Describe the bug Running the example line: adios_reorganize sim.bp sim.h5 BPFile "" HDF5 "" from the documentation creates a segmentation fault. Both with and without the mpirun bit.

To Reproduce

run adios_reorganize, doesn't matter which output back-end is used

Expected behavior no segfault

Desktop (please complete the following information):

OS/Platform: Fedora 31
Build: gcc 9.2.1

Additional context The same bp file seems to read fine using the Python module.
