>Description:
The Intel C++ compiler is supposed to be 100% binary compatible with gcc 3.4.
However, this isn't the case in one specific situaion: if a shared library is
compiled with the Intel compiler, an app linked with the library and then
run-time linked with a library build with g++, the dynamic linker can't find
the __intel_cpu_indicator symbol.
>How-To-Repeat:
Download, and untar http://trolls.troll.no/bhughes/icpc_bug4.tar.gz.  In the
icpc_bug4 directory, type 'make' - this will build libgo.so using icc, then
build and link app with the icc version of libgo.so, then it removes and
rebuids libgo.so with g++.
>Fix:
If it was possible to link with the libimf.so library shipped with the intel
compiler, the problem would be solved, but we used the static version, and the
link places the __intel_cpu_indicator symbol in the shared library instead of
the executable. One possible solution would be to have a small shared library
that defines the __intel_cpu_indicator symbol, and link that before the static
libimf.a library.

State-Changed-Why:  
This looks like an application bug that should be taken upstream to ICC. 
Unfortunately, we do not have the resources to provide a custom fix for this, 
so set the state to "suspended" to indicate that progress on our side is unlikely :( 
However, if you receive any updates on this bug, e.g. from Intel, please drop us a line!
