Bug 23132 – "cannot access frame pointer" comparing two ranges for equality from v2.099.0

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.
