Compiler regression on trust-dns-proto #78598

The 30 Oct. nightly of the compiler cannot compile my project anymore because it crashes while compiling a dependency: trust-dns-proto versions 0.6.3 and 0.5.0. It seems to me that both versions of the library trigger the compiler crash based on the output of the compiler.

Code

I am not sure the code of my project is relevant since it fails in a dependency whose versions are given in the error output.
