These results are posted in dejazilla: https://web.elastic.org/~dejazilla/viewsummary.php?summary=%3D%27%3C5296108F.2020903%40redhat.com%3E%27 The at_var_cu.exp test looks like it might need some closer examination it got a Segmentation fault. The process_by_cmd.stp, process_by_cmd2.stp,32_BIT_UTRACE_SYSCALL_ARGS startup, and global_var-m32 tests also seemed to fail in similar way.
