[Bug translator/22054] New: on 32-bit systems, buildok/twentynine.stp fails


https://sourceware.org/bugzilla/show_bug.cgi?id=22054

            Bug ID: 22054
           Summary: on 32-bit systems, buildok/twentynine.stp fails
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: translator
          Assignee: systemtap at sourceware dot org
          Reporter: dsmith at redhat dot com
  Target Milestone: ---

On the 32-bit systems I've tried (2.6.32-696.6.3.el6.i686 and
4.12.5-300.fc26.i686+PAE), the buildok/twentynine.stp test case fails like so:

====
# stap -gvp4 ../src.copy/testsuite/buildok/twentynine.stp
Pass 1: parsed user script and 460 library scripts using
48980virt/31436res/8408shr/23260data kb, in 290usr/40sys/342real ms.
semantic error: Expecting lvalue expression: identifier '$skb' at
../src.copy/testsuite/buildok/twentynine.stp:5:8
        source:        $skb = 0;
                       ^

Pass 2: analyzed script: 1 probe, 2 functions, 0 embeds, 0 globals using
81120virt/65144res/9816shr/55400data kb, in 2090usr/210sys/2560real ms.
Pass 2: analysis failed.  [man error::pass2]
====

This doesn't happen on 64-bit systems or with the pre-bpf code on 32-bit
systems.
