          Issue ID: 13415
           Summary: '-inline' causes wrong enclosing scope pointer for
                    nested function called from templated struct
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Keywords: wrong-code
          Severity: critical
          Priority: P1
         Component: DMD
          Assignee: nobody@puremagic.com
          Reporter: verylonglogin.reg@gmail.com

This code should run fine:

a.d:
---
struct S(alias func)
{
    void call() { func(); }
}

extern(C) int printf(in char*, ...);

void f(int i = 77)
{
    void g() { printf("i = %d;\n", i); assert(i == 77); }
    S!g().call();
}
---
main.d:
---
import a;

void main() { f(); }
---
Command line (Windows):
---
dmd -c a.d
dmd main.d a.obj -inline -allinst
main
---
Output:
---
i = 0;
core.exception.AssertError@a.d(10): Assertion failure
...
---

`a` module compilation option doesn't matter. Final executable have to be compiled with '-inline' and either '-allinst' or '-debug'.

This may be a root issue for reports Issue 13083, Issue 13244, and Issue 13286.
