vtserver segfault on MontaVista Carrier Grade Linux 3.1

[gazmarsh]

Hi,

I'm currently evaluating VTune for use in profiling my MontaVista Carrier Grade Linux 3.1 application. I have followed the steps for building the remote data collector from app. note 30502201 and in general, VTune has performed well.

Unfortunately I am experiencing a problem when attempting to 'drill down' on one of the modules on the system - namely libc-2.3.2.so from the MontaVista glibc-2.3.2-25.0.27.0500612 rpm.

vtserver exits with a segmentation fault - stack trace as follows:

(gdb) where

Has anyone else seen this / have a workaround?

Installed vtune rpms as follows:

intel-vtune-vtserver-7.2-16940
intel-vtune-ism-7.2-16940
intel-vtune-sampling-rdc-7.2-16940
intel-vtune-lips-2.1-16940
intel-vtune-doc-rdc-7.2-16940
intel-vtune-bistro-2.1-16940
intel-vdk-3.3-99

intel-vdk-src-3.3-99

Regards,

Garry.

Hmm, it appears that the vtserver process has a problem with the debug information present in the .so - stripping the file lets me work around the problem.
