Re: [Valgrind-users] [callgrind] CGAL profiling error, over 100% of instruction count

[Jin T. L. <jl...@co...>]

The version of valgrind: valgrind-3.9.0
HW/OS: Macbook pro retina(core: i7), Ubuntu 12.04 on Parallels. 

Following link has the callgrind file.
https://www.dropbox.com/s/241sovlq14nrxmi/callgrind.tar.gz

I’m not sure the function name,
but the caller of the function is “create_internal_node_use_extension”, incl. is 70.73%
This function is a directly recursive function.
If you see the callees tab, you can see one of the callee takes 408.45%
However, if you see call graph, this callee is disappeared.

I turned on “Relative”, “Cycle Detection”, “Relative to Parent” option in kcachegrind.
