The following code runs fine when you compile it normally, but segfaults when
you compile it with "-profile".  It appears, from looking at gdb and "objdump
-d", that the root problem is that the code jumps to an invalid instruction. 
Note, when you test this code, to use the exact code I show here.  The error
vanishes if you change very much, even things like type or module names:



BEGIN MODULE: "main.d"

module main;

import rule_pattern;
import std.stdio;



template my_chain(RET_TYPES...)
{
  void delegate(RET_TYPES)
  of(ARG_TYPES...)(ARG_TYPES args)
  {
return null;
  }
}



typedef char[] IDENT;



int main()
{
writefln("f");

  auto myChain = my_chain!(IDENT, void delegate(rule_pattern*))
                             .of(delegate void(void delegate(IDENT)) {},
                                 delegate void(void delegate(void
delegate(rule_pattern*))) {});

writefln("a2");

  return 0;
}

BEGIN MODULE "rule_pattern.d"

module rule_pattern;

struct rule_pattern {}

END CODE
