You don't strictly need to wait for nightly to do this, for the `Vec` side of things (unless the feature is enabled) you could simply use the "manual" version of...

Hello, the problem here is that this function is incredibly unsound. A `MemoryBuffer` provides "read-only access to a block of memory" ([docs](https://llvm.org/doxygen/classllvm_1_1MemoryBuffer.html)), which means that when one is made with...

`MemoryBuffer` does not have any lifetime constraints and the slice it receives can have an arbitrary lifetime, which means you can trivially cause use-after-free scenarios

I'm having nearly the same issue running on Windows 10 with criterion 0.3.5 ``` Error: Failed to receive message from Criterion.rs benchmark target disjoint_indices Caused by: An existing connection was...

I don't really remember the context of what I wanted this for, but I believe I wanted to just hand criterion my raw benchmark results in order to enable it...

I made a [minimal example](https://github.com/Kixiron/codespan-salsa) of using `salsa` & `codespan-reporting` to get on-demand computation (so you only calculate spans and stuff for the errors you actually emit)

That's really strange and kinda sounds like a rustc caused thing, have you looked at `cargo build -Z timings`?

Could you try reporting this to rustc, I don't know why it would be infinitely building

Hum, that sounds like it'd be a good cli switch, I'm not entirely sure what would actually be done though

I've also encountered this issue with a pretty similar error ``` error: linking with `link.exe` failed: exit code: 1120 | = note: "C:\\Program Files (x86)\\Microsoft Visual Studio\\2019\\Community\\VC\\Tools\\MSVC\\14.29.30133\\bin\\HostX64\\x64\\link.exe" "/NOLOGO" "C:\\Users\\Chase\\AppData\\Local\\Temp\\cargo-installxK5FlF\\release\\deps\\difft-4c58f491c2051e70.difft.25834a4f-cgu.0.rcgu.o" "C:\\Users\\Chase\\AppData\\Local\\Temp\\cargo-installxK5FlF\\release\\deps\\difft-4c58f491c2051e70.difft.25834a4f-cgu.1.rcgu.o"...
