That is pretty old. Some versions before 0.142 had bugs that could
result in us misplacing probes. But that isn't the issue you are seeing
here, since even if the probe was misplaced it should still not crash
the binary you are inspecting.

If possible, please do try using elfutils-0.142+ (latest is 0.147). Even
though that shouldn't matter in your case.

I was also unable to replicate. Using systemtap 1.2 or current git tip.
elfutils 0.147. kernel 2.6.32-33.el6.x86_64 or 2.6.33.5-112.fc13.i686
