When in GCC compatibility mode, ICC on IA64 does not support asm statements, as shown for instance in http://tinyurl.com/7m3bd. I've googled for this, and the references found seem to confirm this fact. This is currently causing countless test failures in FFT-icc_8.1.30/intel-linux. The proposed patch to boost/detail/sp_counted_base.hpp, though not tested (don't have access to the environment), seems to me will solve the problem: basically, it disables the forwarding to the optimized boost/detail/sp_counted_base_gcc_ia64.hpp on the circumstances described.

Yes, please go ahead. A slightly better fix would be to add an Intel-specific sp_counted_base using <ia64intrin.h>, but only someone with access to Intel on IA64 can do it.

Done.

Far beyond my skills, I'm afraid. In the meantime I hope the patch will do. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo
