Hi,

The following bit of code compiles fine with gcc 3.3 or later, but has
problems with the Intel C++ compiler version 9.1, which produces the
following error message.

Is this a compiler bug, or is there something wrong with the code?

If the former, I'd be grateful for suggestions of a workaround, and if
the latter, please tell me what I'm doing wrong.

Note that the corresponding version with no templates compiles without
problems.

Thanks in advance. Faheem.
