I indeed used lttng-agent-7a8767c, dated 2011-08-12 15:02 ...at both ends. At least for the last trace anyway, and that last trace is as toxic as the others. I need to double-check if a non-Eclipse trace (using tcf-client) will have the same toxicity. I may be inadvertently setting some trace properties differently because the nomenclatures are so different. I'll report on that once it's done. > If the traces are corrupt, this can cause the libtraceread C library to have > a segmentation fault.
