[Bug testsuite/4942] New: kmodule.stp fails on systemtap-20070818 snapshot

[srinivasa at in dot ibm dot com]

My environment is Systemtap-20070818 snapshot,elfutils-0.128 and kernel-2.6.23-rc3.

kmodule.stp fails with below error message. From error it looks like 
===================================

Is there any change in semantics of "log" function?
=================================================
probe end
{
        log("systemtap ending probe")
        log("count = " . sprint(count));  ===> bug is here
}

I tested CVS head and the snapshot and did not see this problem.  I am running a
different kernel, but this doesn't seem kernel related.

What's happening here is:
* the module/function probes were all marked as optional, and for some reason
were all excluded in your kernel build
* this elided body of the handler ("count ++") 
* this in turn removed the only source of typing information for "count" (a number)
* this in turn made sprint (one of severa polymorphic functions) yelp that it
didn't know the type of "count"

Nothing changed with log.
What we need is some combination of:
* a change to the test case to add ", never" to the module/function probes
* a change to the test case to choose some other modules/functions that are
bound to be present in more kernels.

Frank
 You are right, I tried using "never" its working now. So we need to change the
testcase.

Thanks
