    I am spoiled by dotnet and rust error messages. They tell you exactly what the problem is, where it is, and in rust’s case sometimes even how to fix it

    Then there’s C with “segmentation fault”

      1. You are comparing compiler-generated errors and runtime errors
      2. Rust can trigger segmentation fault and bus error too.
      3. GCC’s error messages are very detailed, sometimes can contain suggested solutions.

      For example if I will try to compile helloworld without including stdio.h, gcc will warn implicit declaration of function ‘printf’(by default, almost everyone make it error with -Werror=) and will suggest note: include ‘<stdio.h>’ or provide a declaration of ‘printf’. And runtime error reports are as good as programmer makes them, no matter language program was written in.

      I am spoiled by core dumps(although rust technically has them too).

      Also in context of kernel, it will print stack trace and (if used) will kexec into another kernel that can make core dump or continue working.
