The code below compiles with gcc, but not with Digital Mars C++ (dmc).
Is the code wrong or is there a bug in dmc?


template<typename T> class arr { T x; };

template<void (*D)(const arr<double>)> class ode { };

void fun(const arr<double>) { }

int main() {
ode<fun> odeInst;
return 0;
}

dmc gives the following error message:

ode<fun> odeInst;
^
sim.cpp(9) : Error: need explicit cast to convert
from: void (*C func)(const arr<double >)
to : void (*C func)(const arr<double >)
--- errorlevel 1

Works with VC8, Comeau, and EDG, too. I'd say it's a DM bug.
