Comment # 1 on bug 202 from Sebastien Alaiwan

It seems to occur when std.conv and byLine are used in the same module.
Here's another example which causes link issues:

// cantlink.d
int main()
{
  import std.stdio;
  stdin.byLine().front();
  return 0;
}

void f(char[] s)
{
  import std.conv;
  to!int(s);
}

$ gdc cantlink.d

If the 'char[]' is changed to a 'string', the problem disappears.
