Hello,

I'm surprised by this as well. Boiling down your example to
[bash]class X { template void foo(); }; template void X::foo() { _rdtsc(); }[/bash]
shows the same problem. I've filed a defect ticket for it (DPD200276936).

As solution I've included "immintrin.h" which defines the "_rdtsc()" intrinsic. Does this solution also work for you?

I'm sorry that you seem to have quite some problems with our compiler using variadic template arguments. The more we appreciate your feedback to improve our compiler!

Thank you & best regards,

Yes, #include fixes this issue. Thank you.

I make few more tests and figured out that any intrinsic, used without including the proper header, will trigger this issue.

Hello,

this problem will be fixed in Intel Composer XE 2011 Update 10. It will be available in the near future.

Thank you again for reporting & best regards,
