I get the same error, but in a slightly different context. I tried the case from ZY Zhou on DMD 2.041, and it still fails.
The different case that I'm seeing is this.
This links fine.
real y = 99.5L;
ulong x = cast(ulong) y;
But if I put it after the following call, I get the link error.
BinOp!(ulong, real).P( 99L );
// where P is defined like this
template BinOp(T, U)
{
void Q( U u ) {}
void P( T t ) { Q( cast(U) t ); }
}
Then compiling with -O gets rid of the error. I do have a case where the error doesn't go away with the -O flag. The following is all in main.
BinOp!(ulong, real).P( 99L );
real y = 99.5L;
void Q( ulong l )
{
}
void P( real r )
{
Q( cast(ulong) r );
}
// B: -O doesn't fix this
P( y );
Of course, getting rid of the BinOp.P call gets rid of the error as before.
Sorry if this is confusing. I've attached a file that might show this a little more clearly. Picking line A or one line B by itself will not bring out the error. It involves enabling A and one of the line Bs.
