             Bug #: 14346
           Summary: with inode-uprobes, the dtrace_vfork_exec test fails
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: runtime
        AssignedTo: systemtap@sourceware.org
        ReportedBy: dsmith@redhat.com
    Classification: Unclassified


When the dtrace_vfork_exec.exp testcase is run against a kernel with
inode-uprobes, the dtrace_vfork_exec.exp testcase fails test
'dtrace_vfork_exec2', which is the test run without semaphores.

The test expects output of the form:

  parent - pid: [0-9]+
  parent - child pid: [0-9]+
  child - pid: [0-9]+
  parent - finished

However, the output instead looks like:

  parent - pid: 26659
  child - pid: 26660
  parent - child pid: 26660
  parent - finished

The test passes when run with semaphores.
