Warning when using -xprofile (C++)

Question

Hello!
I experimented with profile feedback optimization in Sun Studio C++ and got tons of warnings when building with -xprofile=use
warning: Profile feedback data for function <function> is inconsistent. Ignored.
I also noticed that all functions mentioned in warnings are either:
- defined in C++ unnamed namespace;
- member-functions of template classes which use members of unnamed namespace as their parameters.
I was able to minimize the case to the following:
$ cat a.cpp
namespace {
template<typename T>
struct P
T* m_p;
P(T* p) : m_p(p) {}
~P() { delete m_p; }
T* get() { return m_p; }
int main()
P<int> p(new int);
++(*p.get());
return 0;
$ # compile for collection
$ CC -xprofile=collect -xO5 a.cpp
$ # run experiment
$ ./a.out
$ ls a.out.profile/
feedbin.lock feedbin.xprof
$ # rebuild using profile info
$ CC -xprofile=use -xO5 a.cpp
warning: Profile feedback data for function __unnamed_KgMkF5gmoLkTE::P<int>::~P() is inconsistent. Ignored.
$ CC -V
CC: Sun C++ 5.10 SunOS_i386 128229-04 2009/11/25
Usage: CC [ options ] files. Use 'CC -flags' for details
Any ideas/solutions/workarounds?
Thanks!

Sorry, the information I gave in the previous message was misleading.
You should update the Solaris patch for the profiling library libxprof.so.1
as well. In general, you should keep all of the patches in the list up to
date since they are inter-dependent.
For x86, the current version of the profiler patch is 119961-06:
% uname -a
SunOS ... 5.10 Generic_120012-14 i86pc i386 i86pc
% /opt/sunstudio12.1/bin/version /usr/lib/libxprof.so.1
version of "/usr/lib/libxprof.so.1": SunOS 5.10 119961-06 Patch 10/07/2009
For sparc, the current version of the profiler patch is 118683-04:
% uname -a
SunOS ... 5.10 Generic_139555-08 sun4u sparc SUNW,SPARC-Enterprise
% /opt/sunstudio12.1/bin/version /usr/lib/libxprof.so.1
version of "/usr/lib/libxprof.so.1": SunOS 5.10 118683-04 Patch 10/05/2009
Note that the Studio compilers use 'fbe' as an assembler, as opposed to using
the standard Solaris assembler /usr/ccs/bin/as . The patch that includes 'fbe'
updates the compiler backend components; it does not update the profiling
support library.
