3.4 after parser merge
>Description:
I suspect that this code is illegal, since the template
keyword for disambiguation is not allowed here:
----------------------------
struct CPU {
typedef int (*pfun)();
template <pfun step1>
static int dispatch();
};
template<int>
static int foo();
template int CPU::dispatch<&template foo<2> > ();
------------------------
Nevertheless, it should not ICE, which it started
within the last three weeks, probably with the new parser:
tmp/g> /home/bangerth/bin/gcc-3.3-pre/bin/gcc -c y.cc
y.cc:11: error: parse error before `template'
tmp/g> /home/bangerth/bin/gcc-3.4-pre/bin/gcc -c y.cc
y.cc:11: error: template-id `dispatch<<expression error> >' used as a
declarator
y.cc:11: internal compiler error: Speicherzugriffsfehler
