systemtap can't find debug info

systemtap can't find debug info

[Hien Nguyen]

I run the systemtap "at_avar_mark" test case on fedora 18 x86_64

and got the following error

Running ./systemtap.base/at_var_mark.exp ...
executing: stap -v ./systemtap.base/at_var_mark.stp -c {/usr/bin/stap 
-p4 -e 'probe begin { log("start")}'}

It seems to me that systemtap can't not find the systemtap-debug info - 
which is installed

[root@ibm-w520 testsuite]# rpm -qa | grep debuginfo

attr-debuginfo-2.4.46-7.fc18.x86_64



I wonder if anyone run into this issue, did I miss some other packages?

Thanks, Hien.

I've duplicated this and filed PR15671 against this issue:

<http://sourceware.org/bugzilla/show_bug.cgi?id=15671>

This one is odd, since it only happens on rpm builds. Can you CC
yourself on that bug?
