Bug ID: 34329
Summary: RHEL 10.2 systemtap 5.6-prerelease sanity checks throw
parse error, other symptoms
Product: systemtap
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: translator
Assignee: systemtap at sourceware dot org
Reporter: mike_itguy at Yahoo dot co.uk
Target Milestone: ---
post build sanity checks throwing errors with RHEL 10.2 and 5.6-prerelease
stock RHEL 10.2 x64. Installed the pre-reqs for build and test of systemtap.
Cloned the systemtap repo on 27/June/2026 (5.6-prerelease) and built systemtap
on RHEL 10.2 x64 bare metal.
After the build and `sudo make install` (the ./configure --prefix=/usr), I ran
the stap sanity checks mentioned
at the bottom of this page https://sourceware.org/systemtap/getinvolved.html
But each sanity test throws a parse-error before completion , although the
second test mentions other symptoms,see below.
Perhaps this is due to the pre-release nature of the repo snapshot at that
date, but I thought it necessary to check so raised this ticket.
Detail of screen-output of first sanity test:
root@localhost:/home/user1/systemtap# stap -ve 'probe begin { log("hello
world") exit () } '
parse error: expected literal string or number
saw: operator '*' at
/usr/share/systemtap/tapset/libvirt_probes-64.stp:204:3
source: *cert = user_string($arg4);
^
1 parse error.

That parse error comes from /usr/share/systemtap/tapset/libvirt_probes-64.stp
which is a file not from systemtap.

Thank you for that. It explains the parse-error. Do you have any suggestions
about the additional symptom from the second sanity test, i.e. the debug-like
output that mentions lost-messages and unexpected-sequences?

Yeah not sure what's up with that, but that large number is 0xffffffe3, smells
like an error code or such. See if that's reproducible, and let's treat that
as a separate bug.
