Segmentation faults in callgraph wizard

Segmentation faults in callgraph wizard

Hi,

I'm running the newest VTune (as of last Tuesday, 2/12/2008) on Ubuntu 7.10 64-bit on a "Intel Core2 CPU 6600 @ 2.40GHz".

I'm trying to use VTune to profile a GNU Radio application. These applications are typically driven by Python scripts which use SWIG to interface with C++ libraries.

I set up the callgraph with the executable /usr/bin/python and the optional command-line arguments to be the python script. Console output looks like this:

In the window in which I started vtlec, I see a bunch of "segmentation fault (core dumped)" lines of output, which makes me think whatever program is doing the static instrumentation is segfaulting.

At the end of this process, the window pops up with the output: "No results were generated for this run. Check the log or output window for further information".

If I try with a python command that just exits (e.g., I pass as the commandline argument a nonexist python source file), the call graph wizard works and gives me results. Any suggestions?

Thanks,
Dan
