[ET Trac] [Einstein Toolkit] #1271: hwloc is segfaulting

#1271: hwloc is segfaulting ---------------------+------------------------------------------------------ Reporter: sbrandt | Owner: Type: defect | Status: new Priority: major | Milestone: ET_2013_05 Component: Other | Version: development version Keywords: | ---------------------+------------------------------------------------------ My efforts to run the ET testsuite fail when system_topology.cc attempts to bind threads to CPUs because hwloc_get_obj_by_depth(topology, pu_depth, pu_num) returns NULL. In the attached patch I check for a null return value and print a warning, then skip setting the affinity.
