vtserver segfault on MontaVista Carrier Grade Linux 3.1

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
#0 0x4069aec6 in CDWARF32Loader::define_files ()
from /opt/intel/vtune/rdc/shared/bin/libdilDWARF32_2.so

#9 0x08053985 in ISMagent ()
#10 0x0804e39f in processSOAPPOSTData ()

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.
