--- Comment #2 from Volker Reichelt <reichelt at gcc dot gnu.org> ---
Here's a reduced testcase. It ICEs with -std++0x since GCC 4.7.0:
========================================================
template<int> struct A {};
void foo()
{
L:
M:
A<(__INTPTR_TYPE__)&&M - (__INTPTR_TYPE__)&&L> a;
};
========================================================
PR79650.cc: In function 'void foo()':
PR79650.cc:11:48: internal compiler error: in convert_nontype_argument, at
cp/pt.c:6598
A<(__INTPTR_TYPE__)&&M - (__INTPTR_TYPE__)&&L> a;
