[Bug c++/14241] New: ICE when returning template class where template argument is a template function

[Bug c++/14241] New: ICE when returning template class where template argument is a template function

[Duff at DIKU dot DK]

The following code:
============================
template <typename T> void f () { }
template <void(*F)()> struct B { };
template <typename T> B< f<int> > g (T) { return B< f<int> >(); }

int main (int argc, char const* argv[])
{
        g(0);
        return 0;
}
============================
If "B< f<int> >" is replaced with a typedef, the program compiles.

The problem exists with both gcc 2.x and 3.x and I have verified it under different distributions of linux 
(and therefor gcc) plus Mac OS X (with apple's modified gcc).

The output from the compiler is:
In function `int main(int, const char**)':
internal compiler error: Bus error

(or segmentation fault on other systems)

Confirmed, but already fixed in GCC 3.4.0. Not being a regression and most 
likely a parser issue, this will not be fixed in 3.3. Thanks for your report.
