[rust-enhanced] include! macro: systemd crash

[bf]

the include! macro can be used to crash systemd and force user to re-login.

I have tested this on linux 6.12.1 with sublime-text and rust-enhanced
plugin but it should affect all situations where rustc is spawned as
child process.

Example:

compile_error!(include!("/dev/zero"));

This will fill up all ram at compile time until rustc is OOM-aborted by
the kernel.

Then the IDE (in my case sublime-text) will try to read the compile
error message via the open pipe to rustc it will also be OOM-aborted.

On my system this results in full systemd crash. User will be shown
login screen again, all programs are closed. Just from compiling rust code.
