>Description:
The attached code gives the following error when compiled with g++-3.2:

exempel.cpp: In member function `void functor<T>::operator()() [with T = P]':
exempel.cpp:24:   instantiated from here
exempel.cpp:16: internal error: Segmentation fault

If a type P is explicitly used instead of the template parameter, everything seems to work well.

Note: The program uses an external library, the Boost Multi Array library. I have notfied the developers of that library as well.
>How-To-Repeat:
g++ g++bug.i

If the parameter to the boost typedefs is not the template type T, but rather the type P directly, it seems to compile.
