           Summary: Segfault "cannot get frame pointer to <function>"
           Product: D
           Version: D2
          Platform: x86_64
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P2
         Component: DMD

This code

import std.functional;
import std.algorithm;

void main() {
    bool b = true;

    bool f(int) { return b; }

    filter!(not!f)([1]);
}

causes the compiler to segfault. I am using no compiler flags or options. I have DMD64 D Compiler v2.062.

On a larger project with similar code, I get the error

/usr/include/d/std/algorithm.d(1288): Error: constructor
std.algorithm.FilterResult!(not, ReadMacroPartialMatch[]).FilterResult.this
cannot get frame pointer to not
/usr/include/d/std/algorithm.d(1310): Error: function
std.algorithm.FilterResult!(not, ReadMacroPartialMatch[]).FilterResult.popFront
cannot get frame pointer to not
/usr/include/d/std/algorithm.d(1288): Error: constructor
std.algorithm.FilterResult!(not, ReadMacroPartialMatch[]).FilterResult.this
cannot get frame pointer to not
/usr/include/d/std/algorithm.d(1310): Error: function
std.algorithm.FilterResult!(not, ReadMacroPartialMatch[]).FilterResult.popFront
cannot get frame pointer to not

But I cannot figure out how to reproduce this error in a small example. I just get the segfault on the example code I posted.

This code

import std.functional;
import std.algorithm;

void main() {
    bool f(int) { return true; }

    filter!(not!f)([1]);
}

causes the error

/usr/include/d/std/algorithm.d(1288): Error: constructor
std.algorithm.FilterResult!(not, int[]).FilterResult.this cannot get frame
pointer to not
/usr/include/d/std/algorithm.d(1310): Error: function
std.algorithm.FilterResult!(not, int[]).FilterResult.popFront cannot get frame
pointer to not

But does not segfault. To my knowledge it should work.

Looks to be a closure bug.

ICE's in gdc also, backtrace:

#0 markAsNeedingClosure(f =
std.algorithm.FilterResult!(not,int[]).FilterResult.this, outerFunc = D main)
#1 checkEscapingSiblings(f = main.not!(f).not!(int).not, outerFunc = D main)
#2 checkEscapingSiblings(f = main.f, outerFunc = D main)
#3 FuncDeclaration::needsClosure(f = D main)
...

The loop condition in markAsNeedingClosure will keep looping until a null pointer is dereferenced as std.algorithm.FilterResult is not lexically nested inside D main.

closure / possibly call by alias bug.

Both examples work without error for dmd 2.064 head.
