shared libraries
Product: systemtap
Version: unspecified
Status: NEW

Assignee: systemtap at sourceware dot org
Reporter: wcohen at redhat dot com
Target Milestone: ---
On x86_64 Fedora 28 when trying the qemu_count.stp example getting a lot of
WARNING messages like the following:
$ stap -v qemu_count.stp
Pass 1: parsed user script and 544 library scripts using

[wcohen@cervelo virtualization]$ rpm -qf
/usr/share/systemtap/tapset/qemu-system-aarch64.stp
qemu-system-aarch64-core-2.11.2-2.fc28.x86_64
[wcohen@cervelo virtualization]$ rpm -q systemtap
systemtap-3.3-1.fc28.x86_64
The problem also appears with systemtap build from a current git checkout on
Fedora28. However, do not see the problem on RHEL7. Suspect that different
info being generated in .note.stapsdt for Fedora 28 and RHEL7.
