Issue: rustc SIGSEGV while compiling & running tests
Labels: I-crash,T-compiler,C-bug

Funny case, getting sigsegv while compiling the tests, but even then I get a working test-suite and I have _no_ idea why rustc is  crashing here.

I've filed it as an ICE as it's techincally a compiler crashing, but I really do not know what to file this as.


### Code

not applicable, the code runs, and the tests run afterwards as well, yet I got a crash in rustc..

### Meta

`rustc --version --verbose`:
```
