Created attachment 43997 [details]
gzipped C++ source code

The attached C++ code, when compiled by recent trunk gcc, does this:

In file included from array_real.cpp:28:
array_tlp.hpp: In instantiation of ‘void ArrayOperator() [with K = double; Z = l
ong int]’:
array_real.cpp:44:32:   required from here
array_tlp.hpp:1703:27: internal compiler error: in inc_refcount_use, at cp/pt.c:
8955
0x63784e inc_refcount_use
        ../../trunk/gcc/cp/pt.c:8955
0x63784e set_refcount_ptr<tinst_level>
        ../../trunk/gcc/cp/pt.c:8994
0x998992 push_tinst_level_loc
        ../../trunk/gcc/cp/pt.c:10152

The new bug seems to exist between revision 259439 and 259515.

I will have my usual go at reducing the code.
