stap-report output

make installcheck stalls on rlimit.exp on ubuntu 24.04.4 dual Xeon 6146.

I built systemtap 5.5 with gcc 13.3 on ubuntu desktop x64 24.04.4, and elfutils
0.190 (both of these from the ubuntu repositories). Afterwards I ran 'sudo make
install' with prefix /usr (thereby replacing the old incompatible version of
systemtap). Then I ran (as root) make installcheck, which ran many tests and
then seemed to hang for hours until I killed it.

This is on a bare metal box, no virtual machine. There is 768GB of DDR4 ram
which might be relevant for the rlimit.exe stalling.

When I run (as root) `make installcheck` it seems to run all the test-files
sequentially in alphabetical order in the directory
../systemtap-5.50/testuite/systemtap.base. There may be approx 299 expect files
in that directory, and the installcheck processed 218 of them (some failures
were reported), but when installcheck reached file 219 of 299  rlimit.exp, the
process seemed to stall. I left it running, but after around 4 hours I used
Control-C/Control-break (to no effect) so from another terminal window as root,
I used `kill -9 which worked. Notice that the machine had not hung, linux
seemed to be operating normally, only the `make installcheck` seemed to be
stuck.

I would like to be able to get `make installcheck` to complete all of the
tests, but that is not currently possible. 

I attach the output of stap-report in file stap-report.txt.

Any suggestions for workaround, or whether I should ignore this, or how to get
the remaining tests to run (or example, by altering or skipping rlimit.exp)
etc?
