--- Comment #1 from William Cohen <wcohen at redhat dot com> ---
This would also be useful for the @entry support. A number of the systemtap
examples fail like in the following way:

TEST
PWD=/home/wcohen/systemtap_write/systemtap/testsuite/systemtap.examples/memory
meta taglines 'test_check: stap -p4 overcommit.stp' tag 'test_check' value
'stap -p4 overcommit.stp'
attempting command stap --bpf -p4 overcommit.stp
OUT semantic error: unhandled multi-dimensional array: identifier '$pages' at
overcommit.stp:6:40
        source:              execname(), pid(), @entry($pages))
                                                       ^

Pass 4: compilation failed.  [man error::pass4]
child process exited abnormally
RC 1
FAIL: systemtap.examples/memory/overcommit build
