[Bug translator/3785] systemtap.sample/poll_map.stp dies on 2.6.18-1.2868.fc6 kernel

------- Additional Comments From wcohen at redhat dot com  2007-01-01 19:39 -------
I have thought about this a bit more and I am wondering if the elfutils-0.123 on
the fc6 machine might be causing the problem. The systemtap is built using
elfutils 0.124 and has it's own shared library installed in a local directory.

Looking at the position of the EIP it looks like it is in sys_munlockall of this
kernel. However, having a probe that only instruments that one function doesn't
crash. The probe is set at 0xc046054aUL the EIP is reported at c0460579:
