--- Comment #1 from Frank Ch. Eigler <fche at redhat dot com> ---
This is unlikely to be a systemtap bug. One way to check is
to analyze the stap module (e.g. stap -p2 -v ...) to see the
PC addresses chosen for the uprobes, to replicate them with
"perf probes", and see if the problem reappears.
A number of significant fixes were made to the kernel uprobes
subsystem in 2014 (after 3.13 was released). Please try again
on a newer kernel.
