broken backtrace in Jetson TK1

I try to use tegra system profiler on the project dct8x8 in samples cuda sdk. I modified the make file, adding the keys compilation -fno-omit-frame-pointer -marm -funwind-tables. Now build the project looks like this:

I profiled application in tegra system profiler with options: Sampling rate: 100 Hz and Collect call stacks: automatic. But while the construction report I appear broken backtraces:

Can this be fixed?

Hi Ghost,
Could you try the latest tool? It should have fixed your issue.

Hi,

I am facing Broken backtraces on my tegra profiler 2.6 when I try to profile my code

Any pointers to resolve these issues?

Thanks,

Hi Ghost,

To resolve issue try use latest tool which is 3.1.
