            Bug ID: 17953
           Summary: systemtap.context/context.exp regressed on RHEL6
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: runtime
          Assignee: systemtap at sourceware dot org
          Reporter: mcermak at redhat dot com

The systemtap.context/context.exp testcase regressed on rhel6/all arches.
Bisecting the source shows that:

* 1c9686814469bd99176394cda1b25caf258bda75 caused ppc64 breakage
* 992b22547d4b85052cbcb7db279b7101a30f799d caused breakage on remaining el6
arches.

For the record, on rhel7 this testcase only works on x86_64.

Could you test this with commit 5160c6f2d840c35a7fd1de5c3d176aa793dc51c9 (or a
later commit) to see if the problem still persists?

There is an issue with commit 992b22547d4b85052cbcb7db279b7101a30f799d that
causes the debug line info not to be stored because one of the initial checks
had the comparison sign backwards. This was fixed in commit
5160c6f2d840c35a7fd1de5c3d176aa793dc51c9.

As for the ppc64 breakage with commit 1c9686814469bd99176394cda1b25caf258bda75,
 if you have the test results, could you attach them, please?

Tested with version 2.7/0.161, commit release-2.6-274-gbabad5b31b70 on top of
kernel-2.6.32-528.el6:


 6.7 S x86_64, i686
-------------------------
FAIL: symfile ()
FAIL: symline ()
FAIL: symfileline in pp ()


 6.7 S s390x, ppc64
-------------------------
FAIL: symfileline in pp ()

I'm attaching logs showing the difference (commit 5700d0b8d349 versus
1c9686814469).


I'm happy to share my testing boxes if needed.
