            Bug ID: 30599
           Summary: Stap probe does not terminate on Kernel Version 6.3
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: runtime
          Assignee: systemtap at sourceware dot org
          Reporter: halamour at redhat dot com
  Target Milestone: ---

When using fedora kernel version 6.3.6-200.fc38.x86_64, running any SystemTap
script with IO will not terminate after Pass 5: starting run unless forced to.  

e.g.  
probe begin
{ print ("hello world\n")
exit () }


Upon downgrading to 6.2.15-300.fc38.x86_64 problem does not appear.
Possibly related to stapio.

--- Comment #1 from Frank Ch. Eigler <fche at redhat dot com> ---
Not sure what was the cause of what Housam observed, but this is working fine
e.g. on 6.3.8-200.fc38.x86_64 .
