import std.stdio;
struct S
{
int i;
void bar()
{
++i;
}
void foo() immutable
{
void delegate() dg1 = &bar;
dg1(); // comment out to fix
void delegate() dg2;
dg2.ptr = cast(void*)&this;
dg2.funcptr = cast(void function())&S.bar;
dg2();
}
}
void main()
{
immutable S s;
writeln(s.i);
s.foo();
writeln(s.i);
}
Without dg1() call, dmd arranges registers's content correctly. However in
presence of dg1 call it incorrectly rearranges them so that [rex.W callq] calls
this pointer, not function pointer.
