Since gdb is printing the pointers as 32-bit values, and pw is not 
64-bit-aligned, it appears that your compiler is using the ILP32 
convention (32-bit int, long and pointer types). I assumed the LP64 
convention (64-bit long and pointer types, 32-bit int) when writing the 
assembly-language code in sp_counted_base_gcc_ia64.hpp because I wasn't 
aware that other conventions were in use on IA64. If the C++ code is 
compiled with an ILP32 convention then the assembly-language code will 
be completely broken. I may be able to adjust the code to work to detect 
the model at compile time and use 32-bit memory accesses if appropriate.
