--- Comment #2 from Stan Cox <scox at redhat dot com> ---
With dyninst-XX and systemtap-XX
The first case now works.  There were some recent changes to stapdyn
environment variable handling as a result of dyninst changes that perhaps
helped.

stap --runtime=3Ddyninst -e 'probe process.function("main") { println("hi f=
rom
dyninst!") }' -c 'ls'
hi from dyninst!
...

However, the ldconfig case, although it now executes, hangs further on:
