--- Comment #2 from agentzh <agentzh at gmail dot com> ---
Yes, it's indeed caused by a gcc version mismatch. The default gcc when running
stap is gcc 4.4.7 while the kernel was compiled by gcc 4.7.3 and 4.8.0. By
explicitly specifying the "-B gcc-4.7" option by running stap, the problem
disappears immediately.

And yeah, I also hope stap can have a way to check such issues automatically to
prevent such weird issues :) I'll think about Josh Stone's proposal above :)
