<br>
I have a headless ParaView build of the HEAD origin/master (commit number 1018) with libOSMesa 10.6.3 as offscreen renderer, to support a Catalyst workflow. Everything works fine, except that the process of MPI-rank 0 will give a segfault when a render window has been used in the catalyst pipeline (this happens also when not running with mpiexec/mpirun).<br>
<br>
I'm not familiar enough with VTK/PV or gdb to try to solve this on my own, so I post the gdb backtrace here in case someone has an idea what is going on. Any clues on how to fix this are welcome :-) Let me know if you need more information.<br>

Best wishes,<br>
