          Issue ID: 23132
           Summary: "cannot access frame pointer" comparing two ranges for
                    equality from v2.099.0
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: regression
          Priority: P1
         Component: phobos
          Assignee: nobody at puremagic.com
          Reporter: chalucha at gmail.com

My library unittest fails with:

```D
/home/tomas/dlang/dmd-2.099.0/linux/bin64/../../src/phobos/std/algorithm/comparison.d(1026,30):
Error: cannot access frame pointer of
`during.tests.api.__unittest_L125_C1.MapResult!(__lambda8, Uring).MapResult`
/home/tomas/dlang/dmd-2.099.0/linux/bin64/../../src/phobos/std/algorithm/comparison.d(1026,29):
Error: none of the overloads of template
`std.algorithm.comparison.equal!().equalLoop` are callable using argument types
`!()(MapResult!(__lambda8, Uring), Result)`
/home/tomas/dlang/dmd-2.099.0/linux/bin64/../../src/phobos/std/algorithm/comparison.d(1030,18):
       Candidate is: `equalLoop(Rs...)(Rs rs)`
tests/api.d(147,43): Error: template instance
`std.algorithm.comparison.equal!().equal!(MapResult!(__lambda8, Uring),
Result)` error instantiating
```

Failing code is here:
https://github.com/tchaloupka/during/blob/9fa519b3a4192486093691aa2e70809773e9426b/tests/api.d#L147

This was ok until v2.098.1.

I've tried to bisect this using [Digger](https://github.com/CyberShadow/Digger)
and it resulted with https://github.com/dlang/phobos/pull/8284

Which seems to be relevant.
