--- Comment #2 from Frank Ch. Eigler <fche at redhat dot com> ---
It would help to have the systemtap.log file rather than the installcheck
console (which is apprx. the systemtap.sum file).

In any case, I asked a little AI pal with access to the sourceware bunsen MCP
(https://builder.sourceware.org/mcp) to look into this report and speculate
about cause.  (opencode, gemini 3.5, "Take a look at systemtap bug 34214, any
initial guesses?")

Its theory is on the stap argument-parsing code for --rlimit-FOO
immediately imposing a setrlimit() during parsing, thus having the first 
--rlimit-as=1 cause an ENOMEM crash, but whose handling may trigger more
crashes.  Should be easy to fix - or change the test case.

Would you like to give this a try?
