I get the same (even when commenting out the first and > third test). But I am unable to replicate it outside the test harness. I've improved the test case, making it more robust, but I think as written it has discovered a real problem. I finally got a reproducer outside the test harness: # lsmod | fgrep stap # staprun ~/.systemtap/cache/c2/stap_c216255bba9c8e0942596f8aa9732125_677.ko & \ > killall staprun; killall stapio [1] 20214 stapio: no process found [1]+ Terminated staprun ~/.systemtap/cach/c2/stap_c216255bba9c8e0942596f8aa9732125_677.ko # lsmod | fgrep stap stap_c216255bba9c8e0942596f8aa9732125_677 34009 0 It appears that if you kill staprun/stapio before the module has a chance to print (the script was a simple "probe begin { printf("hello\n") }'), this bug can happen. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
