            Bug ID: 22117
           Summary: on 32-bit systems, getting "noncontiguous location for
                    base fetch" errors
           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 2.6.32-696.el6.i686 and 4.12.9-300.fc26.i686+PAE we're seeing the follow=
ing
failures:

FAIL: buildok/nfs-detailed.stp
FAIL: buildok/twentytwo.stp
FAIL: buildok/vfs-all-probes.stp
FAIL: buildok/vfs-detailed.stp

Here's a specific failure:

# stap -vp4 ../src.copy/testsuite/buildok/twentytwo.stp Pass 1: parsed user
script and 460 library scripts using 49240virt/31752res/8416shr/23364data k=
b,

Pass 2: analysis failed.  [man error::pass2]
=3D=3D=3D=3D

All the failures are different occurrences of the same "noncontiguous locat=
ion"
error. It might be that this error only happens when trying to get a 64-bit
valie.

These failures only happen with 32-bit platforms. These failures don't happ=
en
with pre-bpf merge systemtap.
