            Bug ID: 24953
           Summary: foreach statement not retrieving correct array values
                    in stapbpf
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: bpf
          Assignee: systemtap at sourceware dot org
          Reporter: sapatel at redhat dot com
  Target Milestone: ---

When using foreach statements with arrays on stapbpf, the incorrect values =
are
retrieved. For example, the following script demonstrates this:

global arr=20

probe begin { arr[1] =3D 1; arr[2] =3D 2; exit() }=20

probe end { foreach ( v =3D v1 in arr) { printf("%d ", v) } }'

'1 2 ' should be printed, but rather '0 0 ' is printed.

--=20
