            Bug ID: 20297
           Summary: parse error: array size out of range on i686
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: runtime
          Assignee: systemtap at sourceware dot org
          Reporter: mcermak at redhat dot com
  Target Milestone: ---

On i686 kernels I seem to be hitting an unexpected problem with array of size N
not being sufficient to accomodate N elements.  This seems to work as expected
on all other arches AFAICT (incl. also single-abi 32-bit arm).

=======
 6.8 S i686 # stap -p2 --poison-cache -ue 'global arr[1] probe oneshot{
arr["a"]=3  }' >/dev/null
parse error: array size out of range
        saw: /usr/local/share/systemtap/tapset/linux/i386/syscall_num.stp EOF

2 parse errors.
WARNING: tapset "/usr/local/share/systemtap/tapset/linux/i386/syscall_num.stp"
has errors, and will be skipped
Number of similar error messages suppressed: 1.
Rerun with -v to see them.
 6.8 S i686 #

The systemtap-2.9-4.el6.i686 doesn't have this problem, so it looks like a
regression.  Investigating further.

Closing out. Not a bug.

--- Comment #3 from Martin Cermak <mcermak at redhat dot com> ---
This behaviour was caused by an unrelated error elsewhere in one of my own
working tapset files.  This problem doesn't happen with clean git sources. 
Thus closed as NOTABUG.
